Current-Voltage (I-V) Characteristics of Poly(vinylidene fluoride)/Potassium Nitrate Composite Thick Film

Abstract

This article describes the experimental results o f the polyvinylidene fluoride (PVDF)/Potassium nitrate (KNO3), composite films. To explain the nature o f ferro electric phase (phase III) o f potassium nitrate (KNO3), we have prepared the composite films o f poly (vinylidene fluoride)/potassium nitrate in the relative amount o f50-50 wt. % by using simple melt pressing. The results o f the temperature dependence o f the capac itance and conductance o f the composite films have been carried out. The current vs. voltage (I-V) characteristics exhibit the polarization current, which is the nature offerroelectricity in the composite films. Capacitance vs. voltage (C-V) measurements have been performed to identify the ferroelectric properties o f the composite films.
