Polymer composite nanomaterials based on thermosetting resins, composites with P-Si and C60 / metal will be created, nanostructures with metal oxides and silicon solar cells will be studied. popup.description2 Ideas: optimization of interface layers of graphene-polymer nanocomposites (GPN) will allow their use as proton-exchange membranes; improvement of photo-thermo-electric conversion in semiconductor thin-film structures is achievable by their illumination, sonochemical treatment, and change in layer thickness and morphology. Hypotheses: change in GPN characteristics by changing the concentration and chemical state of the surface of graphene fillers; thermophysical characteristics of GPN depend on the state of the filler/matrix interface; the state of interface regions in heterostructures can be sonochemically modified; the decomposition of Fe-B pairs is most effective in a certain spectral range of illumination; structuring of the liquid incorporated into the porous silicon matrix is ​​possible; ion and laser irradiation of a metal alloy controls the process of nanocrystal formation in it. Goal: development of physical principles for the creation of new carbon-intercalated and semiconductor thin-film structures for use as proton-exchange membranes and working elements of photo-thermo-electric converters. Tasks: to determine the main patterns of changes in the parameters of synthesized graphene-polymer nanocomposites with recommendations for their use in proton-exchange membranes; to establish interface-dependent patterns of thermal and elastic properties of nanocomposites of various types; to improve the efficiency of photo-thermo-electric conversion of semiconductor thin-film structures by changing the thickness and morphology of the layers; to obtain amorphous-nanocrystalline alloys under the action of ion and laser irradiation.  Product Description popup.authors Horb Alla M.
