Abstract: Biopolymer - an environmentally friendly and harmless polymeric material continues to show good growth potential. Several factors such as soaring oil prices, worldwide interest in renewable resources, growing concern regarding greenhouse gas emissions and a new emphasis on waste management have created renewed interest in biopolymers such as corn starch, Potato starch and arrow root starch etc. Focusing on these interests, a new solid biopolymer electrolytes based on the biopolymer Potato starch doped with different molar concentrations of Ammonium thiocyanate (NH4SCN) have been prepared by Solution Casting Technique. The complex formation between the polymers and the salt has been confirmed by FTIR analysis. From the conduction graph the Polymer electrolyte having 40 mol% Potato starch doped with 60 mol% NH4SCN has low bulk resistance and high ionic conductivity of 3.93×10-4 S/cm at 303 K. Moisture content of the prepared biopolymer electrolytes have been studied by using moisture analysis.
