Recently, more and more attention has been paid to the creation of protective materials on a polymer basis, which have the advantages of low weight, are relatively inexpensive and are capable of being molded. However, to date, the influence of multicomponentity and dispersion of fillers in polymer-filled composites on their electromagnetic properties has been poorly studied and is mainly limited to the frequency range up to 30 GHz, and therefore this area requires further detailed research in order to establish a direct relationship between the efficiency of reflection/absorption of EMF and the electrodynamic parameters of composite structures and to find new approaches to creating a lighter and thinner material with effective absorption of EMF. The aim of the project is to develop a scientific concept for creating multi-component nanocomposite structures (NCS) with controllable electrodynamic parameters based on establishing a correlation between the type of NCS and the electromagnetic response, characterized by high shielding and absorption of microwave radiation. Main tasks: study of the processes of modifying the conductive cluster and changing the interfacial polarization by integrating conductive (CNT, GNP, Fe), dielectric (BaTiO3) and magnetic (Fe, Fe oxides, Co, Ni) nanofillers of various morphologies in the polymer matrix; study of the influence of the composition, morphology and concentration of combined fillers on the electrodynamic characteristics of composites; development of a method for creating composite multi-layer structures with different types of components.
