Cupric oxide nanoparticles CuO NPs can be produced by sol-gel. The copper oxide nanocomposite (CuO/PAG) was prepared by added suspension solution of CuO NPs to polymer blend (PAG) which was prepared by mixing poly acetal resin with gelatin. The nanoparticles morphology is categorized through powder X-ray diffraction (XRD) along with scanning electron microscopy (SEM). Using the Scherrer formula, the average crystallite size of CuO nanoparticles can be computed. The analysis of powder XRD shows a formed monoclinic CuO phase with 15 nm average particle size. There is good agreement between the data obtained by XRD and microscopic measurements. The electrochemical characteristics for synthesized nanocomposite have been examined. The dielectric performance for a sample involving dielectric loss, AC conductivity and dielectric constant has been recorded under numerous frequency levels.
