description: The subject of the graduate qualification work is "Analysis of the dielectric response of multicomponent nanocomposite materials based on porous glasses". The dielectric properties of the structure of both initial and modified with carbon and TiO2 nanocomposites based on 6 nm porous glasses (PG6) with embedded KNO3 (PG6+C+KNO3) and NaNO2 (PG6+TiO2+NaNO2) have been studied. Dielectric was studied on cooling from 450 to 300 K at frequencies of 0.1 Hz Ã· 3 MHz. Structural studies showed that in composites with KNO3, modification of the surface of porous glass with carbon leads to changes in phase composition, and in composites with NaNO2, modification of the pore surface with titanium oxide adds the content of the crystalline phase of NaNO2. Carbonization of porous glass reduces the permittivity and conductivity of the composite. Addition of titanium oxide leads to the growth of permittivity and conductivity of the composite. From the analysis of the dielectric response showed that the main contribution to the NCM composition is the charge polarization at the interfaces. The DC conductivity and activation energies were estimated.
