Investigation of the Dielectric Properties of PVA/PVP/SiC Nanostructures
0133–0138 (2023)

PACS numbers: 72.80.Tm, 77.22.Ch, 77.22.Gm, 78.20.Ci, 78.67.Sc, 81.07.Pr, 82.35.Np

This work is aiming for a fabrication the polyvinyl alcohol/poly(N-vinyl-2-pyrrolidone)/SiC (PVA/PVP/SiC) nanostructures and studying their dielectric properties to use in different electrotechnical and electronic fields. The PVA/PVP/SiC nanostructures are prepared by using casting method with different concentrations of polymer blend and nanoparticles. The dielectric properties of PVA/PVP/SiC nanostructures are studied at frequency range from 100 Hz to 5 MHz. The results show that the dielectric constant, dielectric loss and A.C. electrical conductivity of PVA/PVP blend are increased with an increase in the SiC-nanoparticles’ concentration. The dielectric constant, dielectric loss and A.C. electrical conductivity of PVA/PVP/SiC nanostructures are changed with an increase in the frequency.

Key words: nanostructures, SiC, blend, dielectric parameters, electrical conductivity.
