The goal of the project is the development of new hybrid nanocomposites (HNCs) using a mixture of graphene-like two-dimensional (2D) nanostructures as a filler and, based on comprehensive theoretical and experimental studies of the relationship between the methods of obtaining, the type, structure, phase composition of 2D nanostructures, the nature of their spatial distribution in HNCs and electrodynamic, optical and thermal properties to obtain materials that will simultaneously have high characteristics of shielding and absorption of electromagnetic radiation (EMR) in the microwave and infrared ranges and low thermal conductivity.

The main idea of the project is to create new polymer nanocomposites (PNs) based on the use of a mixture of graphene-like two-dimensional (2D) nanostructures to obtain materials, which simultaneously have high shielding and absorption characteristics of electromagnetic radiation (EMR) in the microwave region of the spectrum and low transmission of EMR in the infrared region, to solve a number of urgent problems of defense, security, economy and society of Ukraine. During the implementation of the project stage, comprehensive studies of multicomponent nanocomposites based on two-dimensional graphene-like structures with different types of filler i) conductive 2D nanostructures (GNPs, GNPs modified with Co3O4, Fe), (ii) transition metal dichalcogenides - MoS2 and WS2, both in the form of microcrystalline particles and few-layer structures and mixtures of the above graphene-like 2D nanostructures were сarried out.The influence of the type, morphology, phase composition, structure of the indicated graphene-like 2D nanostructures, and the nature of their spatial distribution in the PCM on the main patterns of changes in the electrodynamic characteristics such as the values of permittivity and magnetic permeability and the coefficients of transmission and reflection of electromagnetic waves when changing the type of 2D structures in the short-wave and infrared parts of the spectrum has been established. The electrodynamic characteristics of PCM with a hybrid filler in the microwave frequency range of electromagnetic waves were investigated. It was shown that the use of a mixture of graphene-like 2D nanostructures consisting of several layers (few layers) leads to a synergistic effect, which leads to both a qualitative change in the electrodynamic characteristics of the PCM and a change in the nature of their interaction with the EMR formatting the absorption mechanism of interaction of CM with EMV. It was established that PCMs based on two-dimensional micro- and nanoplate
