Preparation and Structural Characterization of PVP-CH3COONa Based Polymer Films

Abstract

PVP based polymer electrolyte films were prepared by dissolving sodium acetate with different wt.% compositional ratios by solution cast technique. XRD revealed the crystalline phase of the prepared samples. XRD pattern demonstrated a wide peak at 29.35° attributed to the host polymer indicating orthorhombic cross section showing semicrystalline phase. FTIR and Raman studies affirmed to identify the functional group of the materials, bond formation between the dopant salt and the host polymer. The dispersion of salt particles in the polymer film impacts the segmental movement of the particles in the polymer matrix. With the arranged NCPEs, a rechargeable cell was prepared and its electrochemical investigations were studied.

Keywords: Solid polymer electrolyte films, solution cast technique, XRD, FTIR, Raman and cyclic voltammetry studies
