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

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