Electrical behavior of proton-conducting chitosan-phosphoric acid-based electrolytes

Dielectric and AC conductivity studies have been carried out for chitosan-based proton-conducting electrolytes. Chitosan-phosphoric acid (CP) and chitosan composite (CPS) electrolytes were prepared using the solution cast method. In both systems, the frequency dependence of epsilon(r), M-i and tan d...
