Abstract
To fill the gap of earlier works for the nanocomposite based on a ferroelectric of triglycine sulfate (TGS) and a dielectric inclusion of cellulose nanoparticles (CNP), the present study provides experimental results for investigating anomalous switching properties via analyzing the features of dielectric (P-E) hysteresis loops. Different dielectric content of CNP (5, 15, 30, 50, 70 wt.%) was chosen. The P-E loops were measured at temperatures placed at the same distances from the phase transition point for all compositions. Besides, the influence of humidity (RH = 30, 60, 80, 100 %) was also investigated. It was clarified that the increase in cellulose content and relative humidity caused the increase in coercive field, accompanying the transformation of hysteresis loops from saturated into unsaturated ones. The nature of these anomalies was proposed to be associated with the role of hydrogen bonds in the composite.
