Studies of proton conducting polymer electrolyte based on PVA, amino acid proline and NH4SCN

Proton conducting polymer electrolytes based on PVA, amino acid proline and NH4SCN were prepared by the solution casting technique. An increase in the amorphous nature of the polymer electrolytes was confirmed by X-ray diffraction analysis. DSC measurements showed a decrease in Tg with increasing sa...
