Proton conducting polymer blend electrolytes based on MC: FTIR, ion transport and electrochemical studies

In this work, the free-standing plasticized solid polymer electrolyte films were made utilizing methylcellulose (MC) and dextran (DN) doped with ammonium fluoride (NH4F) and plasticized with glycerol by a typical solution casting approach. Based on the characterizations, MC-DN-NH4F electrolyte has b...
