This study is aimed to investigate the electrical properties of biopolymer gel as functions of polymer concentration and temperature. To perform this study, gellan gum was used as a biopolymer, which is a bacterial polysaccharide. The gellan polymer in solution dissociates into polyelectrolyte and it forms polyelectrolyte gel under a suitable condition. We studied the ionic conductivity variation of this gellan gel electrolytes with varying polymer concentration from 0.5 wt.% to 3.5wt.% which exhibit a slight increase in ionic conductivity at room temperature. In addition to different polymer concentration, we investigated the effect of temperature dependent electrical property from 300 C to 800 C and the Arrhenius plot obtained from this temperature dependence of conductivity revealed a stronger network with increasing polymer concentration.
