Abstract

Solid Polymer electrolytes based on I-Carrageenan with sodium nitrate was synthesized via solution casting technique. Distilled water was used as a solvent. AC impedance measurements were carried out in the frequency range of 42Hz to 1MHz. Maximum ionic conductivity 1.0915×10-5 Scm-1 was obtained for 0.4wt% of sodium nitrate at room temperature. From AC impedance data,dielectric parameters were obtained and the same was analyzed.
