Effect of ZrO2–CuO Nanofiller on the Optical Constants and Optical Conductivity of Biopolymer

Creating polymer nanocomposite specimens is carried out using the solution-casting technique.The specimens are comprised of a host matrix of polyvinyl alcohol (PVA), in which varying concentrations of zirconium oxide (ZrO 2 ) and copper oxide (CuO) nanoparticles are incorporated, spanning a range from 0 to 6 wt.%.The nanostructures composed of PVA-ZrO 2 -CuO exhibit notable attributes, such as low expenses, enhanced resistance to corrosion, favourable optical properties, and a relatively lightweight nature compared to alternative nanosystems.The optical properties are measured within the wavelength range () from 200 nm to 840 nm.Optical properties show that the absorption coefficient, refractive index, and dielectric-constant real and imaginary parts for PVA-ZrO 2 -CuO nanocomposite increase with increasing concentrations of the ZrO 2 -CuO nanoparticles; so, the optical parameters at wavelength 400 nm: absorption coefficient (), refractive index (n), extinction coefficient (k), real ( 1 ) and imaginary ( 2 ) parts of dielectric constants, and optical conductivity ( op ) for PVA are enhanced by about 1540%, 100%, 2216%, 302%, 1116%, and 3025%, respectively, with adding of 6 wt.% ZrO 2 -CuO nanoparticles.The performance of the PVA-ZrO 2 -CuO nanocomposites suggests that they possess favourable characteristics as optical nanomaterials in the domains of electronics and optics. .
