Vibrational Spectroscopic and Optical Absorption Studies on PVA Based Polymer Electrolytes

Abstract:

Article Preview

The electrochemical methods of energy storage and conversion are of great interest for many practical applications. In the present investigations, PVA: MgSO4 based solid polymer electrolytes were prepared at different weight percent ratios using solution cast technique. FTIR spectroscopic studies were carried out to verify the complexation of the dopant with polymer. Force constant measurement was also carried out to ensure the interactions of polymer with salt. Optical absorption studies were carried out in the wave length range 200 to 600 nm. Absorption edge as well as bandgap values were evaluated. In order to ensure the ionic conduction of these electrolyte systems, transference number measurements were also carried out. The dominant conducting species were ions rather than electrons. These studies will help in verification or in investigating the feasibility of these electrolyte systems in polymer batteries, fuel cells, and other electrochemical systems.
