Abstract
Iota carrageenan purification was done by dissolving iota carrageenan powder in water. The purified iota carrageenan powder was analyzed by using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy and X-Ray Diffraction (XRD) analyses. The powder was used to form a purified iota carrageenan film based solid polymer electrolyte. Ionic conductivity value of the film was determined by using Electrochemical Impedance Spectroscopy (EIS). The conductivity value for purified iota carrageenan was 1.57 × 10−5 S cm−1 higher than iota carrageenan film. The films were analyzed by using ATR-FTIR, XRD and Field Emission Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy (FESEM-EDX). Electrochemical stability of iota carrageenan was improved after purification and had more ionic conduction as compared to iota carrageenan without purification.
