The project is aimed at using the expertise that involved in consortium entities acquired in materials science. The consortium consists of three representative national institutes: INCD for Chemistry and Petrochemistry – ICECHIM Bucharest, INCD for Electrochemistry and Condensed Matter - INCEMC Timisoara and INCD of Chemical Pharmaceutical - ICCF Bucharest, and of two prestigious universities: University POLITEHNICA of Bucharest and the University of Bucharest and a remarkable institute of Romanian Academy: Institute of Macromolecular Chemistry – Petru Poni Iasi. Although having great

tradition and noteworthy results, the first five institutions face a series of problems, from the lack of financial funds, equipment and the aging employees for ICCF and partly for INCEMC and ICECHIM, to the lack of highly qualified staff required for recent investments in equipment for all 5 institutions. In this respect, the project attempts relaunching the activity in the first 5 institutions of the consortium, by putting together the existing competencies, so as to develop new technologies in order to obtain new materials with high performance properties. Given that, 3 of the research teams are specialized in polymers (ICECHIM, Petru Poni and UPB) the developed technologies will use the polymers as intermediates or as a component in the finished product. To this end it is envisaged getting the titanium nitride for prosthetic coatings via inorganic-organic polymer nanocomposites, obtaining photocatalytic materials and antibacterial coatings by sol- gel reactions, obtaining of short-life or one-time use biomaterials from aliphatic polyesters and

micro or nanocellulose and the development of new polyphase materials with medium or long life, based on biopolymers, through 3D printing. The project intends the full use of A1, A2, B and C checks in order to increase the institutional performance of partners.

Project 1:„Innovative process for synthesis of titanium nitride ceramics via nanocomposite polymer hybrids for biomedical application”

The multidisciplinary project intends to develop a ceramic powder of TiN, with high quality and performance parameters, through an innovative fabrication process, for biomedical applications such as prostheses.

For the purpose of developing new advanced materials, the procedure will utilize integrated technology and processing techniques that are used in industrial appliances, together with nanotechnology specific methods

The purpose of the proposal is to obtain titanium nitride ceramics from hybrid polymeric composites by starting from a synthesized, porous inorganic structure.

The technology proposes a new approach for developing materials that generate a unique class of ceramics with distinctive characteristics, such as mechanical and thermic properties superior to similar materials.

The project proposal is completely new not only in our country, but on global plan as well, by using supramolecular technologies for fabricating TiN from porous TiO2 (host-guest polymerization).

The experience of the researchers, along with well-balanced research teams and adequate infrastructure, greatly improve the chance of success.

Project 2:“Eco-friendly nanostructured hybrid materials for surface protection against deterioration caused by microorganism and pollutants”

 Project 2 aims to produce smart coating materials that have advanced protection properties against the development of biofilms and deposit on surfaces such as stone, paper and metal.

Metallic and/or inorganic nanoparticles coatings will be synthetized by sol–gel process using supercritical CO2, to achieve a minimal energy consumption and a manufacturing process with a low degree of pollution.

Predictive models will be developed for antifungal and antibacterial properties, depending on the nature of nanoparticles that are included in the hybrid matrix. A series of tests will be carried out on the materials obtained, in order to validate biofilm prediction models with high biodegradability, under various environmental conditions.

Therefore, an optimization based on scientific basis of the formula of hybrid materials for smart coatings is desired, in order to simultaneously achieve a self-cleaning capacity, protection against pollutants and a prolonged antifungal/ antibacterial effect.

Proiect 4: „Innovative hybrid materials with photocatalytic properties”

- The aim of the project is to design and produce hybrid materials with photocatalytic properties, in order to obtain self-cleaning coatings in natural or artificial light.

The original approach consists in combining the synthesis of hybrid materials containing oxidic photocatalysts, doped with metallic/polycycloketone complex dyes, with the deposition of these materials on different surfaces (glass, plastic), in order to obtain a series of special physico-chemical properties.

Another innovation is the integrated approach of the classic types of synthesis (sol-gel method) and the unconventional ones (microwave–assisted hydrothermal process).

The project has two development directions – (1) Creating oxidic photocatalyst structures doped with dyes from the class of complex metals / polycycloketone for sensitizing in the visible spectrum, increasing the efficiency of catalytic photodecomposition, and through direct incorporation in hybrid film-forming materials; (2) obtaining hybrid film-forming materials and the description of some that contain oxidic photocatalysis , as well as testing them in auto-cleaning processes after depositing on different surfaces (glass, plastic).

Also, the project envisages the practical application of the new photocatalysts, obtained by synthesizing water-based alkyd film-forming materials, with self-cleaning properties.

The development of photocatalytic nano-structured hybrid materials and ecological technologies contribute to the sustainability and competitiveness to continue national research through: (1) The development of ecological processes energetically efficient and producing technologies; (2) - Researching Activities which approach key aspects of the impact on health and environment; (3) Actions that allow identifying and approaching major obstacles for innovation

The balanced character and the experience of the researchers and research teams involved, together with an appropriate infrastructure, will lead to the successful implementation of the proposed project.

Project 1:„Innovative process for synthesis of titanium nitride ceramics via nanocomposite polymer hybrids for biomedical application””- BIOTiN

Stage 1-1: “Formulation and verification of the conceptual model regarding the synthesis of

hybrid inorganic- organic nano structures  based on porous titania and their processing in TiN for biomedical applications” 

This multidisciplinary project aims at developing, through an innovative manufacturing process, an original TiN ceramic powder, having high quality and performance parameters, suitable for biomedical applications such as prostheses. In order to develop new advanced materials, the approach will utilize an integrated technology and processing techniques that are used in industrial appliances, but also nanotechnology specific methods. The purpose of the project is to obtain titanium nitride ceramics from hybrid polymeric composites by starting from a synthesized, porous inorganic structure. The technology proposes a new approach for developing materials that generate a unique class of ceramics with outstanding characteristics, such as improved mechanical and thermal properties, in comparison to other conventional similar materials.

Specific Objectives: O1. consists of formulation and development of an experimental technology concept for manufacturing of advanced ceramic powders. The technology will be developed in order to obtain a new TiN via composite polymer hybrids, obtained through radical polymerization of a vinyl monomer in pre-synthesized porous TiO2. Subsequent carbonization steps of the polymer and the treatment of TiO2-Carbon composites at high temperatures and under controlled atmosphere have been developed. Biocompatibility tests (toxicity, biological/chemical reaction) will be performed in order to increase the bioperformance for possible application in prosthetic coatings; O2. consist of proving the feasibility and utility of the new technology for the ceramic powder production line, with the subsequent validation of the manufacturing technology; O3. isrepresented by dissemination of scientific results at national and international level. 

Titanium nitride (TiN) is an important technological material with various applications, based on its unique properties. This material can be described as a biocompatible one that exhibits the property of inhibiting bacterial colonization. TiN coatings have shown promising results in terms of blood tolerance, with a near-zero hemolytic percentage. Due to its biocompatibility and excellent hemocompatibility, besides application in microelectronics, anti-corrosion and antireflection coatings for displays, TiN has a wide range of medical applications such as medical devices, dentures, hip joint materials and heart valve replacement. Because TiN coatings are nontoxic, they can be used to make or cover various implants, particularly orthopedic.

In the first stage, there were elaborated: 6 Research reports on: (1) obtaining/characterization of the host inorganic structure (TiO2) through various innovative methods with economically accessible precursors; (2) host-guest polymerization of a vinyl monomer in the synthesized inorganic matrix; (3) elaboration of complex characterization protocols by correlating structure-property parameters, using techniques for advanced materials; (4) obtaining/characterization of Titania-Carbon composites for subsequent transformation into TiN; (5) transformation of Titania-Carbon composites into TiN and description of the property set for the obtained ceramic powder; (6) examination of ceramic powder for potential biomedical application. Three research jobs were created (2 at IC – ICECHIM, 1 at P2 – INCEMC). According to the evidence presented on the platform, 3 research jobs were created, by employing 3 research assistants under legal circumstances, in agreement with the declaration of the general manager. The availability of the positions has been made public on www.euraxess.gov.ro and www.jobs.ancs.ro. 6 scientific communications have been achieved and the results have been disseminated by presenting 5 posters and 1 oral presentation at an international symposium.

            Based on the obtained results, it can be noticed that the performance indicators programmed for Project 1 in Phase 1 have been fully achieved.

            The prepared nanoparticles were characterized in 3 activities, by both, structural (FT-IR, RAMAN, XRD) and morphological (SEM, TEM) methods. The antibacterial properties testing of synthesized nanoparticles has been the subject of another activity.

            Following the performed analyzes, it was found that the synthesis method directly influences the morphology and the size of the nanoparticles, having an indirect effect on the biological activity too.

            In the case of testing the action of nanoparticles on biofilms formation, it was found that AgNPs have the ability to combat the formation of biofilms generated by the two strains used, with an inhibition percentage of more than 50%, for the samples with addition of cetyltrimethyl ammonium bromide. For the ZnO and CuNPs samples, the obtained results suggest a moderate antibiofilm activity for both strains tested, P. putida and B. subtilis. PIBF values obtained in antibiofilm testing suggest the need for optimization of nanoparticles and an additional investigations in order to increase the effectiveness of their biological action.

Project 3: “Biomaterials from aliphatic polyesters and micro- and nano-cellulosic modifiers for short-life and disposable products” (ESTERPACK)

Stage 1-3: Development of new bio-alloys from aliphatic polyesters and thermoplastic bioelastomers 

The “Biomaterials from aliphatic polyesters and micro- and nano-cellulosic modifiers for short-life and disposable products” (ESTERPACK) is an innovative and complex project, which aims to develop a new material (a bionanocomposite) and a new synthesis method that can be easily scaled up. The biomaterial obtained within this project is intended for food or drugs packs, single-use medical instruments, medical sample storage containers, short-life or disposable products in large quantities that are difficult or impossible to recover. This project aims to replace petroleum-based polymers with recyclable polymers from renewable resources, to reduce the pollution caused by using plastic packaging. Due to the realization of products from biodegradable polymers, their impact on the environment is substantially reduced.

Polyhydroxyalkanoates (PHAs) present many of the requirements of alimentary and medical packing materials. They are susceptible to hydrolytic degradation in the environment and alive systems, and can be processed with equipment used for polyolefin or other synthetic plastic materials that present a property set similar to conventional plastics. Mechanical properties of PHA are dependent on the structure of the base monomers, as well as on the molecular weight of the polymers, varying between rubber-like elasticity and the rigidity of a crystalline textolite. Short link PHA can be characterized by its rigidity and fragility. Instead, the ones with 6-14 carbon atoms have properties similar to elastomers.

Thermoplastic polyurethanes can lead to very different properties (such as mechanical, flexibility and biocompatibility), depending on the nature of components that make up the soft segments, the hard segments or the chain extenders. The mechanical properties of the TPU can be adjusted by simply changing the ratio between flexible and rigid segments or by using reactants with different properties. For this reason, they are extremely interesting as packaging materials and medical devices that represents the target of this project.

Low thermal stability, low stability during processing and high brittle behavior are the main reasons, as well as the high price, that prevents the widespread use of PHA in the food packaging and medical products industry. The use of PHA elastomers with medium chain length with biodegradable sequences eliminate the disadvantages mentioned above, due to the use of polyhydroxybutyrate (PHB) modifiers in order to obtain bio-alcohols for packaging, including medical ones.

The project has two development directions: (i) manufacturing elastomeric PHA copolymers with a medium chain length and (ii) obtaining controlled synthesized polyurethanes, that present a component or several biodegradable components. Both procedures are designed to increase the flexibility and ductility, in order to eliminate the brittle character and to improve processing behavior of PHB/PHBV. The first approach, in which bio-alloys from aliphatic polyesters and mPHA modified with nanocellulose were obtained, use only renewable and 100% biodegradable materials.

            In stage I, the research report on the selection of strains producing elastomeric PHA and growing mediums specific for biosynthesis has been elaborated. The microbial biosynthesis of elastomeric PHA and fermentative biosynthesis of PHA model has been studied. Bio-alloys were obtained from aliphatic polyester and elastomeric polyhydroxyalkanoates, and analysis reports were made on the physical, structural and morphological characterization of obtained bio-alloys. Several types of polyurethanes elastomers with biodegradable sequences have been synthetized. The analysis reports on characterization of synthetized polyurethanes elastomers were attached and the nanocellulose functionalization method was presented. Next will be studied the development of a bionanocomposites materials from aliphatic polyesters with various modifiers and cellulose.

 

 

PROJECT 4: “Innovative Hybrid Materials with Photocatalytic Properties- FOTOMAH”

Stage 1-4: Identification of preliminary synthesis in order to obtain oxidic type photocatalytic structures.

At this stage of the project, the following activities were carried out:

1. Preliminary synthesis of the formation of TiO2 structures by hydrothermal method;

2. Preliminary research on the identification of parameters for the synthesis of materials with TiO2-dye (complex metal/polycycloketone class), by sol-gel process and by microwave-assisted hydrothermal process respectively;

3. Preliminary tests to observe: compatibility of the photocatalytic structures with the dye from complex metal/polycycloketone class, photocatalytic activity and antibacterial effect;

4. Dissemination of results through: participation at national/international conferences, article. 

- TiO2 nanoparticles as such and doped with Ag and Fe were synthesized by the hydrothermal method at different autoclave temperatures.

- Materials with TiO2 as such and sensitized with dye (phthalocyanine dye) were obtained by sol-gel process and by microwave-assisted hydrothermal process respectively, using different silane agents.

- Realized studies have confirmed that TiO2 sensitized with phthalocyanine dyes show good results regarding photocatalytic degradation effect on organic dyes such as methyl orange and methylen blue.

- Study regarding the selection and adaptation of a method to assessing the antibacterial activity of thin film products obtained from materials with TiO2 has been elaborated.  

 

 

Project 5 NEW DURABLE MATERIALS BASED PE BAZA IN RENEVOBLE POLYMERS  FOR 3D PRINTING (3D-LONG-LIFE)

Stage 1-5: Design, realization and characterization of new durable materials based on renovable polymers for 3-D printing

             The designing of new polymeric materials requires the simultaneous consideration of both the necessities of the targeted applications and of the specific techniques involved in their transformation into a finished product. Sustainability is defined as the property of polymeric materials to withstand the environmental stresses during lifetime so as not to endanger the proper functioning. Selection of the  polymers that can be used to achieve these materials requires consideration of the present strategy related to the new plastics economy which aims to replace fossil carbon (polymers from conventional resources) with renewable carbon (renewable polymers or chemically modified renewable polymers) through modern technologies. In this context, the goal of the project 40 -2018 / 5 (3D-LONG-LIFE) is to obtain new renewable, durable, polymeric materials compatible with 3D printing, possibly the third technological revolution in the world. The new polymeric materials will be realized by innovative methods of physico-chemical modification of polylactic acid through controlling the properties that insure the durability, namely breaking behavior (through balance rigidity - breaking energy absorption capacity) and thermal properties. PLA is a renewable polymer, with very good processability but with no durability properties. The innovative modification method involves controlling the morphological structure of polylactic acid by generating crystalline / amorphous variable ratios and, as the case may be, controlled crystallization rate, so that the energy absorbed by the material prior to breakage and thermal stability have values specific to durable applications. For this purpose, the renewable polymer will be modified with toughening modifiers and / or nucleation  and / or reinforcing / or stereo-complexing agents. In order to achieve 3D printing through the melted filament techniques, the melt of these new materials must have a flow speed that is characteristic to the profitable production procedures, knowing that the shear rates developed during extrusion do not exceed 100s-1.

In order to achieve the new durable materials, the project partners, who work as a team but each with well-defined responsibilities, have designed and have developed in 2018 the experimental models for obtaining and characterization of these materials. The partnership between the project partners is based also on close cooperation for the interpretation of own results and for the correlation of the materials properties with the modification method. In 2018, the partners have realized laboratory researches both to achieve the new materials (CO) and the characterization specimens  (CO) and  to characterize the new materials (P1, P2, P3, CO). The DSC thermograms (P1), the micrographs in polarized light (P2), the SEM micrographs (P3), along with the XRD diffractograms (P3)  and the  melt flow in Griffits spiral (P1) or in extensional field (CO) clearly highlights the stereo-complexation and/or the nuclear  and/or the reinforcement effects on which  the obtaining of the new, sustainable renewable materials, compatible with 3D printing are based.

The report briefly presents the partial results obtained by the project partners in 2018. The obtained results have shown both that the approached research direction is feasible and, during 2019, the characterization researchers with other methods (TEM etc.) will be continued. Also, next year, the correlating of functional properties with modification solutions, the study of the suitability of the new material with 3D printing, the selection of the interest formulations and the optimizing of the mechanical and thermal behavior according to the interests of the sustainable applications and of the method of the processing into finite product will be done. Depending on the results, other directions for increasing the sustainability of the PLA will be addressed.

The obtained results were disseminated by presenting 3 posters at an international symposium and a PhD dissertation, on the project subject, is underway. According to the evidences presented in the platform and the general manager declaration two jobs were created under legal conditions, as research assistants. The two posts have been launched by publishing on the sites www.euraxess.gov.ro and www.jobs.ancs.ro. Based on the results obtained, it is estimated that the indicators for  stage 1 have been fully achieved by all the partners.

Component Project No.2:“Nanostructured hybrid materials obtained by«eco-fiendly»methods for the surfaces protection against damages caused by micro-organisms and pollutants”- MAHIN

Stage 2-2:“Preparation and characterization of nanostructured hybrid materials by «eco-friendly» non-polluting methods

               

Component project no.2 (PC_2) aimed within the second stage the development by «eco-fiendly» methods of new hybrid coatings with multiple functionality, with antibacterial and self-cleaning effect, to protect the various surfaces against the effects of pollutants and biological attacks with pathogens. During the second stage, the planned activities were carried out to fulfill the proposed objectives and were carried out activities aimed to obtain and characterize the nanostructured hybrid materials by non-polluting methods - «eco-friendly». At this stage of the project two scientific objectives were envisaged:

                - A. Optimization of the parameters for obtaining metallic nanoparticles (Cu, Ag, ZnO, CuO) with superior antibacterial properties by «eco-friendly» methods - the bioextract assisted method - and their characterization;

                - B. Obtaining of the nanostructured hybrid materials based on of metallic and oxide nanoparticles combinations in film-forming silane matrices and their characterization.

                Therefore, it was considered the preparation of intelligent materials for coatings with advanced properties of protection against the development of biofilms and deposition on different surfaces. Also, an area of very important interest in the development of modern materials was the use of various types of nanoparticles, which have antibacterial effect.

                Cu, CuO, Ag and ZnO nanoparticles have been developed in the project, which have promising advantages as non-expensive alternative to other biocidal agents. In order to achieve this first objective of the stage, the following activities were carried out: A2-2-1 “Obtaining vegetable extracts for the «eco-friendly»synthesis of metallic particles”; A2-2-2 “Obtaining metallic nanoparticles (Ag) with superior antibacterial properties through «eco-friendly» methods - the bioextract assisted method”; A2-2-3 “Obtaining metallic nanoparticles (Cu) with superior antibacterial properties by«eco-friendly»methods - the method assisted by bio-extracts”; A2-2-4 “Obtaining metal oxide nanoparticles (ZnO, CuO) with superior antibacterial properties by«eco-friendly» methods (in supercritical and with plant extracts)”; A2-2-5 “Obtaining metal oxide nanoparticles (ZnO, CuO) with superior antibacterial properties by«eco-friendly» methods (in supercritical and with plant extracts)”; A2-2-6 “Optimization of the parameters for obtaining the metal oxide nanoparticles (ZnO, CuO) by the Design of Experiment method (DoE)”; A2-2-7 “Characterization of obtained nanoparticles (Cu, Ag, ZnO, CuO) by optimized methods: FT-IR, UV-VIS”;A2-2-8 “Characterization of obtained nanoparticles (Cu, Ag, ZnO, CuO) by optimized methods: XRD, TEM” and A2-2-9 “Characterization of obtained nanoparticles (Cu, Ag, ZnO, CuO) by optimized methods: XRD, SEM”.

                All the proposed activities were successfully carried out, according to the planned schedule, and the results were materialized in: 1 scientific stage report; 1 stage financial report; 1 audit report; 6 new jobs created in research; 5 training (research)/ training and work visits; 1 laboratory technology; research services offered (realized) by using the available research infrastructure; common RDI program correlated with the institutional development plan of each partner (collaboration for the submission of research projects; participation in annual symposia).

                The project will continue in the next stage with the optimization of the nanostructured hybrid materials and with thefunctionality demonstration of the obtained coatings.

 

 

Component Project nr. 3: Biomaterials from aliphatic polyesters and micro- and nano-cellulosic modifiers for short-life or single-use products (ESTERPACK)

Stage 2-3: Development of bio-nanocomposites from aliphatic polyesters with various modifiers and cellulose

 

Within this stage, the elastomeric polyhydroxyalkanoate product with controlled composition and its biosynthesis technology was developed. Several representative variants of elastomeric polyhydroxyalkanoates were analyzed, both morphologically and structurally, as well as the composition of the copolyesters.Bioalloys from polyhydroxybutyrate and representative variants of elastomeric polyhydroxyalkanoates were made by melt blending, which were characterized in terms of thermal, mechanical and morphological properties. The optimum recipefor elastomeric polyhydroxyalkanoate was selected and the technology for the obtaining of the bioalloy with elastomeric polyhydroxyalkanoate was developed.Bioalloys of polyhydroxyalkanoates and thermoplastic polyurethanes with biodegradable sequences were also made. Bioalloys containing polyurethanes were characterized in order to select the best polyurethane and the composition of the bioalloy. Bioalloys containing the optimum variant of polyurethane and nanocellulose were obtained and characterized in terms of rheological, mechanical and physical-chemical analysis. The work will continue with the patenting of the results with applicative interest.

 

 

Component project  nr. 4:“Innovative Hybrid Materials with Photocatalytic Properties”

Stage 2-4: Realization and characterization of nanostructured hybrid materials/films with photocatalytic effect

 

At this stage of the project, the following activities were carried out: 1) Realization of oxide-type structures (TiO2 doped with metallic ions) with photocatalytic activity in the visible domain; 2) Synthesis and characterization of the oxide-type photocatalytic sol-gel materials, doped with dyes (metalliccomplexes/polycycloketonesclass) and of the oxide-type photocatalytic materials obtained through the hydrothermal process assisted by microwave;3) Testing the antimicrobial effect of the oxide-type photocatalytic materials doped with dye; 4) Realization of coatings on different surfaces types (glass, plastic), using hybrid materials,doped with dye,obtained by sol-gel process and through the hydrothermal process assisted by microwave; 5) Obtaining the pelicogenic materials by incorporating of photocatalytic materials into water-based paint formulations; 6) Testing and evaluation: photocatalytic effect for coatings realized onto different types of surfaces (glass, plastic), photodegradation resistance of binders in paints prepared in the presence of photocatalytic materials;7) Dissemination of results through: participation at national/international conferences, publication of articles.

In this stage, it were obtained: 2 types of non-doped TiO2 nanocrystals, 4 types of TiO2 nanocrystals doped with Ag and 4 types of TiO2 nanocrystals doped with Fe (2% and 3% concentrations, respectively) synthesized by the hydrothermal method, at different autoclaving temperatures (150 °C and 200 °C).

Oxide-type photocatalytic materials doped with dyes (metallic complexes/polycycloketonesclass) were synthesized by the sol-gel method. Sol-gel solutions were synthetized in acidic medium, using silane precursors with different hydrophobic functional groups. These solutions were deposited onto glass and plastic surfaces in order to achieve coatings with anti-reflective, self-cleaning, photocatalytic effects. Homogeneous and uniform films, with hydrophobic properties, were obtained. The photocatalytic films were realized using dispersions of non-doped TiO2 and TiO2 sensitized with dye (iron phthalocyanine).For testing of photocatalytic effect, a methylene blue solution was used as a standard contaminant. The absorbance of the films was monitored by Vis spectrometry at different time intervals, by irradiation with visible light.

The TiO2 films modified with nano-structured metals were realized by the hydrothermal process assisted by microwave. The preparation method of the catalyst ensured a uniform deposition and incorporation of the transition metals in the TiO2 films.

Recipes have been formulated to obtain paints with self-cleaning effect based on TiO2-type photocatalysts sensitized with dyes with mixed azomethine-phthalocyanine chromophore. Two paints were obtained - one interior paint based on acrylic polymer and the other exterior paint based on acryl-styrene polymer. The tests regarding the self-cleaning activity show that the photocatalysts used have a relatively similar behavior, achieving the destruction of the methylene blue dye in about 3 days.

Dispersions of non-doped TiO2 and TiO2 sensitized with dye (iron phthalocyanine) presented an insignificant antimicrobial effect,tested as such on Gram-negative microbial strains Escherichia coli (ATCC 8739) and Candida albicans (ATCC 10231), at a microbial inoculum concentration of 105ufc/ml. The bactericidal effect of TiO2-Ag and TiO2-Fe nanocrystals, synthesized by the hydrothermal method, was evaluated using cultures of bacteria belonging to the Escherichia Coli. Analyzes show that TiO2-Ag nanocrystals exhibit better bactericidal efficiency than TiO2-Fe nanocrystals.

All the proposed activities were successfully achieved, and the results were materialized in: 1 scientific&financial stage report; 1 audit report; 4 laboratory methodologies (hydrothermal method sol-gel process, hydrothermal process assisted by microwave, recipes for obtaining paints); 1 evaluation/testing report of the antimicrobial effect, the photocatalytic effect for the coatings realized on different surfaces, the photodegradation resistance of the films; 4 published articles; 1 accepted article; 15 scientific communications; work visits.

 

Component Project nr. 5 : New durable materials  based on renewable materials for 3D Printing (3D-LONG-LIFE)

Denumire Etapa 2-5: Achievement of new durable materials based on renewable polymers  compatible with 3D printing. Material complex characterization 

 

The design of the new polymeric materials implies the simultaneous consideration of both the requirements of the applications of interest and those characterising the transformation into a finished product technique. The purpose of the project 40 -2018 / 5 (3D-LONG-LIFE) is the achieve new renewable materials, durable, compatible with 3D printing considering the physico-chemical modification of polylactic acid, renewable polymer with very good melt-processbiity but without durability properties. Thus, innovative methods that allow the management of the durability properties through controlling the balance of rigidity - absorption capacity of breaking energy and thermal behavior were selected. The methods of controlled crystallization that allow the organize of the morphological structure by generating variable crystalline / amorphous ratios so that the absorbed energy before breaking and the thermal stability to have programmed values, specifically for the durable applications, were considered. For this purpose, the regenerable polymer was melt compounded with nucleation agents and / or reinforcing agents and / or stereo-complexants. The paper presents the 2019 results obtained in the stereocomplexing of polylactic acid in different dextro-levo compositional ratios so that, depending on the intensity of the specific (+) / (-) attractions, the establishment of nucleation centers leading to materials of interest for sustainable applications to be possible.

                The stereocomplexed compounds were obtained by CO and the new morphologies were characterized by all partners: CO- transmission electron microscopy (TEM) (works in progress), P2 - polarized light microscopy (POM), P3 - X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM). The chemical structure of stereocomplexed compounds was studied by CO by Fourier Transformed Infrared spectroscopy (FTIR). CO has also identified, together with P1, the thermal properties through Differential Scanning Calorimetry (DSC), after removing the thermal history, both polymers used for stereocompletion and stereocomplexed compounds. P2 measured both the molecular masses of the stereocomplexed polymer, before and after the melt compounding as well as the dynamo-mechanical properties of the selected compound as having the maximum stereocomplexing effect. The rheological properties of the melts were studied by CO (extensional field flow) and P1 (injection spiral flow). P1 also identified the mechanical properties, mainly the tensile strengths. In order to test the flow properties, CO performed the experiments on shapeing the new materials as filament and the 3D printing behavior of the obtained filament. The filament ovality was studied by the P3 partner by visualizing the SEM mirographes of their cross-section and the defects of the 3D printed items obtained using the new filaments were analyzed by the P1 patener using the images obtained at the Computer Tomograph (CT). The complex characterizations of material have led to very good correlations of structure- properties characterizing the new compounds which have been used in the material selections. The analysis of the results, their interpretation and the decisions regarding the continuation of the works was carried out by the CO together with all the partners P1, P2, P3. The results obtained in 2019 showed that the addressed research direction is feasable, following in the next stage to be  continued with characterization works  considering other methods (TEM, etc.), and with studying the suitability of the new materials for 3D printing through the molten filament method, the selection of the variants of interest and the optimization of the mechanical and thermal behavior of the selected materials according to the interests of the durable applications and the processing into finished product by 3D printing.

The obtained results were disseminated by publishing an article, presenting 7 posters at 4 international symposiums and a communication at a work shop. The development of a doctoral thesis with a topic related to the subject of the contract is also in progress. The two young ACS who started from 1.01.2019 have resigned on August 12, 2019 because of their own conclussions that they are not compatible with the research work field and that they want to develop careers in other fields. For this reason, starting with 07.10.2019, two other young ACS were hired, who currently occupy the positions 164 and 165 in the list of the contract staff. All the employment documents are legal and are presented in the contract platform. Based on the obtained results it can be appreciated that all result indicators have been fully achieved.
