Effects of Carbonization on Electrophysical Properties of Cellulose-Based Nanocomposites with Triglycine Sulfate

Abstract

In this study, a ferroelectric nanocomposite was prepared from triglycine sulfate (TGS) with cellulose nanoparticles (CNP) pretreated at different carbonization temperatures. The results showed that along with the increase in electrical conductivity, the phase transition temperature of TGS decreased significantly with increasing carbonization temperatures due to the partial destruction of interaction between CNP and TGS during cellulose carbonization. The dielectric measurements were performed under a weak electric field (2 V/cm) in the frequency range of 10⁻³–10⁶ Hz. The work provides deeper insights on the influence of dielectric components on the properties of ferroelectrics.
