Abstract
Polymer nanocomposite of poly(vinyl chloride-co-vinyl acetateco-2-hydroxypropyl acrylate) copolymer (PVVH) doped with different concentrations of Copper oxide nanoparticles (CuO NPs) is prepared using the casting technique method. The prepared nanocomposite samples are characterized using X-Ray Diffracted (XRD), Transmission Electron Microscope (TEM), Attenuated Total Reflection- Fourier Transform Infrared (ATR-FTIR), and optical properties are studied using the Ultraviolet-Visible technique (UV-Vis). XRD and ATR-FTIR of the prepared sample confirmed the interaction and complexation between PVVH and CuO NPs. Optical properties such as bandgap energy and Urbach energy indicate that the addition of CuO NPs into PVVH polymer induced variations in the number of available final states as a function of composition ratio. Also, CuO NPs changed the electronic structure PVVH by doping via deformation potential, formation of localized band states, and Coulomb interaction.
