Dielectric and ac conductivity studies on Polyvinyl alcohol/ Calcium oxide nanocomposite films have been studied in the present work. Calcium oxide nanopowder is synthesized by Low Solution Combustion method. The films were prepared by solution-casting technique. The prepared films have been characterized by X-ray diffraction (XRD) analysis. The XRD pattern of pure PVA shows a characteristic peak at 20° indicating its semicrystalline nature. The crystallite size of these nanoparticles is found to be ~44 nm. The dielectric permittivity, dielectric loss of PVA/CaO nanocomposites were reported. ac conductivity measurements were carried out and reported.
