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...

Structure, morphology, and optical properties of polyacrylamide/poly (vinyl alcohol) (PAM/PVA) polymer blend containing MnO₂ nanoparticles at different concentrations

Manganese Dioxide (MnO2) nanoparticles were incorporated into a Polyacrylamide/Polyvinyl Alcohol (PAM/PVA) polymer blend via solution casting to investigate the influence of MnO2 content (0.1, 0.5 and 1.0 wt%) on the composite’s structural and optical behavior. The novelty of this work lies in demonstrating that the in...

Design of PVA based nanocomposite via tungsten trioxide Nanoparticles incorporation with low thermal emissivity and enhanced optical parameters

Poly (vinyl alcohol) (PVA) is a flexible and chemically durable polymer. However, the broad optical band gap and the insulating nature of PVA restrict its employment in sophisticated optoelectronic devices. In the present study, the solvent casting approach has been effectively used to manufacture eco-friendly PVA/...
