Synergistic enhancement of charge transport, dielectric behavior, and impedance response in Cu/ZnO dual-nanofiller-loaded NaAlg/CMC biopolymer nanocomposites for biodegradable solid polymer electrolytes
ZnO nanoparticles were synthesized via a sol-gel method and then incorporated as Cu/ZnO dual nanofillers into sodium alginate (NaAlg)/carboxymethyl cellulose (CMC) biopolymer composite films using the solution-casting technique. The structural, dielectric, electrical, and impedance characteristics of the prepared films...
