Abstract<\/b><\/span><\/span>

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 300C to 800C and the Arrhenius plot obtained from this temperature dependence of conductivity revealed a stronger network with increasing polymer concentration.<\/span><\/div>Keywords:<\/b><\/span> Biopolymer, Bacterial Polysaccharide, Polyelectrolyte Gel, Gellan Gum, Conductivity<\/span>
