Proton (H+) transport properties of CMC–PVA blended polymer solid electrolyte doped with NH4NO3

This present work investigated the proton (H+) conduction behavior of the blended polymer solid electrolyte (BPSE) derived from carboxymethyl cellulose (CMC) and polyvinyl alcohol (PVA) that was doped with ammonium nitrate (NH4NO3). The properties of this CMC-PVA-AN BPSE were evaluated using Fourier...
