Conductivity studies on plasticised PEO/Chitosan proton conducting polymer electrolyte
The effect of ethylene sulphite (ES) content on the conductivity, morphology and nature of polymer electrolytes based on polyethylene oxide (PEO) and chitosan blend doped with ammonium nitrate (NH(4)NO(3)) has been analysed in this study. The films produced by the solution cast technique were kept i...
