ION TRANSPORT IN PROTON CONDUCTING PVA BASED POLYMER ELECTROLYTE

K. P. Radha, G. Gurulakshmi

Abstract :

Proton Conducting Solid Polymer electrolytes have been prepared by using Poly (vinyl alcohol) PVA doped with Ammonium Fluoride (NH4F) in different molar ratios by Solution Casting Technique. The ionic conductivity of the polymer electrolyte has been determined by ac impedance spectroscopic techniques in the frequency range 42 Hz to 1 MHz. The highest ionic conductivity has been found to be 6.9X10-6 Scm-1 for 85 mol% PVA: 15 mol% NH4F polymer electrolyte at an ambient temperature. Wagner’s DC Polarisation technique confirms that the ionic conductivity is influenced by mobility and diffusion coefficient of cations (H+NH3) present in the salt NH4F .
