摘要: κ-Carrageenan is an anionic polymer extracted from marine red algae. In order to increase conductivity of the κ-carrageenan, carboxymethyl κ-carrageenan was synthesized by reaction with monochloroacetic acid. A electrolyte comprising and prepared solution-casting technique. The films were characterized Reflection Fourier Transform Infrared spectroscopy (ATR-FTIR) investigate presence complexes. Electrochemical Impedance Spectroscopy conducted obtain ionic conductivity. Ionic found addition group on carrageenan. achieved for 5.34×10-7 S cm−1 2.02×10−4 cm-1, respectively.
