Spectroscopic Study on the Film of Polyvinyl Alcohol and Carboxymethyl Cellulose as Polymer Electrolyte Materials

Abstract

Abstract Polymer electrolytes have emerged as a powerful platform in the progress of more efficient energy storage devices. In this study, polymer electrolyte materials (PEM) was successfully prepared using drop casting method. A spectroscopic study of the film were prepared by variying the ratio of the volume (PVA/CMC) at 100/0, 75/25, 50/50, 25/75 %. The functional groups were investigated using fourier transform infrared (FTIR) spectroscopy. The crystallinity degree obtained by X-ray diffraction (XRD). Their transparency degree were observed by UV-Vis spectroscopy. The ionic conductivity studies obtained by electrochemical impedance spectroscopy (EIS).
