The goal of the project is to develop the physical basis for the creation of new magnetoelectric polymer composites (MPC) based on carbon-containing magnetic shell structures (CMOS) and to establish the patterns of formation in them of abnormally high absorption characteristics of electromagnetic radiation (EMR) in the short-wave part of the microwave range on the basis of complex theoretical and experimental studies of relationships connection between methods of obtaining, structure, phase composition of CMOS, nature of their spatial distribution in CM and electrodynamic properties. As part of the work on the third stage of the NDR, the microwave characteristics of CMOS with different types of shells, namely carbon nanoparticles of different morphologies (nanotubes, graphite nanoplates (GNP), carbon nanoparticles decorated with magnetic nanoparticles (Fe, Fe3O4) with different concentrations of magnetic nanoparticles on the nanocarbon surface); a mixture of nanocarbon (GNP, CNT) and magnetic (Co3O, BaM, Fe, Fe3O4) or dielectric (MoS2) nanoparticles were investigated. The influence of the type of CMOS, their morphology, phase composition, structure, nature of spatial distribution in CMs on the mechanisms of formation of electrodynamic and microwave characteristics has been established. A scientific concept and technological schemes for the creation of highly efficient absorbing materials of the short-wave UHF range based on carbon-containing magnetic shell structures (CMOS) have been developed, depending on the structure and type of CMOS, within which the main requirements for the creation of magneto-electric polymer composites (MPC) based on carbon-containing magnetic shell structures (CMOS) with abnormally high absorption rates of electromagnetic radiation (EMR) have been formulated.  Product Description popup.authors Vovchenko Ludmyla L.
