Electrical Impedance and Proton Conductivity Studies of Polymer Electrolyte Materials

Abstract

Solid electrolyte at different composition of 50% PVA + 50 % PVP + x% NaH2PO2 are prepared using solution casting techniques. The prepared materials of polymer matrices are characterized through several techniques such as XRD, FTIR spectroscopy. The electrical conductivity of the sample is determined through measured impedance data at different frequencies and different temperatures. The electrical conductivity is calculated in the order of 10-8 Scm-1 . The water uptakencabability is also analysed. Proton conductivity is also analysed for vatious atmospheric condition.
