Interaction of structural phases, processes of formation and controlled control of the composition of optical centers, channels of dissipation of excitation energy and transfer of charges in hybrid oxide-carbon nanostructured composites. Subject of study. The role of mechanisms of physical interaction of phases and interfaces in hybrid oxide-carbon nanostructured composites in the formation of their mechanical, optical, luminescent, photo- and electrically conductive characteristics. The goal of the project is to find out at the atomic-molecular level the mechanisms of the interaction of components and the role of transition layers in determining the mechanical, optical, thermal and electrical conductivity characteristics of nanocomposites based on glass and nanocellulose matrices with hybrid filling. It was found that the peculiarities of the temperature behavior of the physical characteristics of cellulose-based composites, in particular in the area of phase transitions, the sizes of cellulose particles, the formation of clusters and their self-association, are determined by the network structure and the strength of hydrogen bonds of the transition layer (hydrate-solvate shell). , which change under the influence of impurity ions and temperature. Based on the comparison of experimental data with the results of theoretical and computational studies, the peculiarities of the interatomic interaction of oxide (chromate) and carbon (graphene and tubes) nanomaterials in the composite materials and the possibility of monitoring such interaction by optical methods. Comprehensive studies, using various experimental and computational methods, revealed the formation of an intermediate nanometer-thick interface layer between particles in crystalline nanoscale powders doped lanthanum vanadate and between crystalline particles of complex oxides and the matrix in oxide glass-ceramics.
