Abstract:

Artificial intelligence tools (neural networks and genetic algorithms) will be used in order to find the most appropriate reaction conditions for obtaining and characterization of new polysulfone-silsesquioxanes membranes impregnated with ionic liquids (PS-POSS-IL) (with predetermined characteristics) as new materials suitable for CO2 capture and storage. Starting from a set number of experiments, in which new types of PS-POSS-IL will be prepared and characterized by changing the reaction conditions (including use of different polysulfones, different silsesquioxanes and a different content or different type of ionic liquid), a data base will be elaborated in order to use it further for modeling with artificial intelligence instruments (neural networks and genetic algorithms). In this way the best reaction conditions can be chosen for obtaining the best PS-POSS-IL membranes as superior materials for adsorbtion/ separation of the CO2. In the first stage of the project, the polysulfones will be obtained and characterized, then the needed silsesquioxanes. Thereupon the membranes will be elaborated from the previous obtained materials, using the phase inversion process. After the membranes will be prepared, they will be characterized for determining the most conducive conditions for manufacturing membranes with the highest CO2 adsorption performance, for their use in separation of CO2, using the artificial intelligence tools (especially neural networks).

Abstract:

Silicone elastomers are important for an increasing range of science and engineering applications and, as a result, their use grows exponentially every year. Silicone-based dielectric elastomer polymers are soft polymeric materials that bring together the properties required for actuation and energy harvesting: large energy density, fast response times, operation in air, long lifetimes, and low Young’s modulus as well as high value for breaking strain.

Many of the properties of silicones, such as high humidity stability and the stability in a wide range of temperatures, recommend them as excellent materials, environmentally friendly for electronic applications. In view of these aspects, my approach will be oriented towards combining the advantages of the two types of materials: metal complexes and silicone polymers in order to obtain new materials, capable of being processed in thin layers, easy to handle and resistant, with dielectric elastomer properties. The greatest advantage of using metal complexes based on siloxane ligands for obtaining silicone polymeric composites is given by the presence of siloxane sequences which ensure a favorable interaction with the matrix, in order to obtain the desired properties. The addition of metal complexes into polysiloxane matrix represents for a strong improvement of the dielectric properties of the resulted materials.

Abstract:

The project aim is to bring developments in the metal-containing materials field by the preparation of new metal-organic networks using ligands with high flexible siloxane spacer between the complexing groups. Networks having single metal ions or polynuclear clusters as nodes will be prepared. The later will be obtained and subsequently used as secondary building units (SBUs) or generated in situ concomitantly with the network formation. Original di- tetra- and polycarboxylic acids as well as amine ligands containing siloxane moieties will be used as SBUs for the metal-organic structures infinitely extended into one, two or three dimensions (1D, 2D or 3D, respectively) via more or less covalent metal-ligand bonding. The siloxane moieties confer flexibility to the networks, thus structural adjustment through rotations and twists of structural units are expected, leading to better uptake of different guest molecules. Both building blocks (siloxane ligands and metal clusters) and networks prepared on their basis will be fully characterized from structural point of view by using adequate techniques (elemental, spectroscopic, X-ray diffraction). The specific properties (as for example: sorbtion behavior, magnetic, catalytic, biological, etc.) will be evaluated in order to identify possible applications of the new materials.

Abstract:

Starting from the incompatibility of polysiloxanes with most of the organic polymers, the project aims to increase the knowledge on tailoring the biphasic morphology in siloxane-containing systems, in order to obtain nanostructured materials with special properties and potential top-field applications. We will try to bring new insights into the structure-morphology – properties relationships of siloxane-containing multifunctional materials. New organo-siloxane systems (copolymers, polymer blends, polymer-dispersed systems) will be obtained and studied to observe nano-organization in solid state, in melt or in solution and to understand the influence of the biphasic morphology over bulk and surface properties. The synthesis of siloxane-containing copolymers with various architectures will be realized by polycondensation or polyaddition reactions, starting from preformed macromers. The structures will be confirmed by spectral methods (NMR, FT-IR) and their properties will be investigated by DSC, DMA, UV-VIS spectroscopy, polarized light POM. The biphasic morphology and nanostructuration will be evidenced by TEM, SEM, AFM, XRD and XPS. The potential of siloxane based surfactants or liquid crystals as nanoreactors or nanoconteiners will be investigated. We will test the preparation of nanoobjects, including polymeric nanoparticles, by nanoprecipitation or polymerization/polycondensation reactions in nanoreactors consisting of biphasic organo-siloxane supramolecular assemblies. The results will be evaluated for subsequent use as disperse phase in polymer blends and as delivery vehicles. Mostly biocompatible/biodegradable materials will be designed and waterbased formulations for medical and personal care use will be explored.
