description: This work is devoted to the study of the dielectric properties of the initial and modified Al2O3, TiO2 and carbon nanocomposites based on porous glasses of 7 nm (PG6) with embedded NaNO3. Dielectric studies were carried out at cooling from 470 to 300 K at frequencies of 0.1 Hz to 3 MHz. Modification of the surface with aluminum oxide practically does not affect the dielectric properties of the NCM at low frequencies. Carbonation of porous glass leads to a decrease in Îµ and Ï at low frequencies. When titanium oxide was added at low frequencies, an in-crease in the dielectric permittivity and conductivity of the composite was revealed. It was determined that at high frequencies, the dielectric permittivity of NCM is mainly determined by the dielectric permittivity of embedded materials. There was also a significant decrease in the conductivity at high frequencies of NCM with a modified surface compared to the original sample, which can be explained by a decrease in the size of sodium nitrate clusters and their lower connectivity. To ana-lyze the dielectric response, the Profit application program was used, and it was shown that the main contribution to the dielectric response of all NCM is made by charge polarization at the boundaries of sodium nitrate grains. The second relaxa-tion process is associated with the hopping conductivity of sodium ions inside and between clusters. DC-conductivity was also evaluated, and activation energies were determined.
