Structure–property relation in copper nanoparticles-based PVA/PVP composites

Abstract

Copper nanoparticles composition-based polyvinyl alcohol/polyvinylpyrrolidone (PVA/PVP) composite films were prepared for select concentrations. AC conductivity, dielectric permittivity, UV–visible and FTIR studies along with X-ray diffraction analysis were carried out on these composites. From this conductivity study, DC conductivity was estimated along with hopping potential, hopping length and thermal conductivity using power law of the frequency-dependent AC conductivity. A correlation study of these parameters using functional analysis method to establish structure–property relation in these composites was also carried out.
