Synthesis and Characterization of Nanocrystalline CuO Embedded in Polymer

Nanocomposite consists of Copper II oxide embedded in poly isopropanol has been synthesized by refluxing method using CuCl2 as a precursor, KMnO4 as an oxidising agent and isopropanol act as both solvent and polymer. The surface morphology of the nanocomposite were characterized by SEM and XRD. The optical properties were characterized by UV/Vis and PL studies and the dielectric properties of the nanocomposite material was calculated through capacitance and impedance values from AC impedance technique. The size of the synthesized nanocomposite was found to be in the range of 28 nm to 60 nm. The calculated energy gap from UV/Vis spectrum was 5eV which falls in the range of insulator. The calculated dielectric constant for CuO nanocomposite was found to be 21.47 and hence it may be used in gate dielectrics and passive components.
