Electrophysical properties of matrix composites nanocrystalline cellulose – triglycine sulfate

Abstract

Dielectric dispersion for a composite based on nanocrystalline cellulose with triglycine sulfate in the frequency range from 1 mHz to 1 kHz at different temperatures from room temperature to the phase transition temperature of the composite (∼ +54°C) in a weak measuring field (1 V·cm−1) was investigated. The obtained results showed the presence of two relaxation regions: the characteristic for the bulk of triglycine sulfate linear dielectric dispersion (10 Hz – 1 kHz) associated with the irreversible motion of domain walls and a significant dispersion region at lower frequencies from 1 mHz to 10 Hz related to the Maxwell-Wagner-Sillars interfacial polarization.
