Abstract : In this study, the films of PVA and CuO nanocomposite were synthesized using a simple solution casting technique. The produced films' optical and structural characteristics were thoroughly investigated. Copper oxide nanoparticles in 0.1–0.4 weight percent concentrations were implanted in the PVA film. Copper oxide nanoparticles were incorporated in polypyrrole and PVA host matrix to prepared films, as evidenced by X-ray diffraction (XRD) tests that revealed their existence in the PVA film without the emergence of extra impurity peaks. XRD tests verified the findings, which showed that the copper oxide nanoparticles belong to the monoclinic phase. The production of semicrystalline PVA polymer was reflected by the appearance of a peak at 2θ = 19.4°. The produced nanoparticles had an average crystallite size of roughly 0.52 nm. FTIR analysis was also employed to confirm the vibrational bands of the films. The findings also demonstrated that when the concentration of CuO nanoparticles increased, the dielectric characteristics improved because of the creation of polarization and an increase in the density of states. Additionally, it was noted that the development of charge transfer complexes caused the optical conductivity of the composite films to increase as the concentration of nanoparticles.

Keywords : CuO Nanoparticles, PVA, XRD, Dielectric, Conductivity.
