文摘

Sodium ion conducting polymer blend thin films are of technologically interesting due to the tuned physical and electrical properties with wide variety of applications like sodium sulphur batteries, thermoelectric generators, electrochemical sensors, etc. sodium ion conducting composite blend polymer electrolyte films, based on poly vinyl alcohol (PVA) and poly(vinyl pyrrolidone) (PVP) complexed with NaCl were prepared by solution casting technique. The prepared films were characterized by various methods. The complexation of the salt with the polymer blend was identified by X-ray diffraction and Fourier transforms infrared spectroscopy. DSC was used to analyze the thermal behavior of the samples and the glass transition temperature is low for the highest conducting polymer material. The Frequency and temperature dependent of electrical conductivities of the films were studied using impedance analyzer in the frequency range of 1 Hz–1 MHz. The higher electrical conductivity of 50 PVA:50 PVP:15 wt% NaCl concentration has been found to be 1.747 × 10−3 Scm−1 at room temperature. The electrical permittivity of the polymer films have been studied for various temperatures.
