The work is devoted to the study of the formation of metal- and carbon-containing composites, biocomposites as promising functional materials for alternative energy, and elucidation of the influence of different carbon nanostructures on the electronic and mechanical properties of the obtained composites. Establishment of local structure of disordered carbon nanomaterials obtained under the action of high-energy influences with determination of their quantitative characteristics of average and topological order.
It is established that expanded graphite - titanium nanocomposites are characterized by a slight change in elastic properties with a significant change in electrical conductivity, which is accompanied by an increase in the maximum value of electrical conductivity to a concentration of 50 wt. % due to the increase in the area of contacts between the particles of the composite and the increase in free electrons in the carbon component during their transition from metal particles. It is shown that during mechanical activation treatment in the structure of graphite there is a continuous transition from crystalline to amorphous state with graphite-like type of the middle order.
The formation of carbon-containing biocomposites based on various forms of carbon nanostructures and amino acids has been carried out. In the case of mechanosynthesis of biocomposites, it was found that their conductive properties are determined by the structural and morphological parameters of the templates on the basis of which they were formed. For biocomposites formed by deposition, it was found that their morphological characteristics are due to the adsorption of organic components on the surface structure of carbon templates. A decrease in the specific surface area of biocomposites was found in comparison with the initial templates due to the filling of the developed surface and the existing pores with aminoxylot molecules.
