عنوان انگلیسی Characterization Effect of Copper Oxide and Cobalt Oxide Nanocomposite on Poly(Vinyl Chloride) Doping Process for Solar Energy Applications
چکیده انگلیسی مقاله The optical properties for pure poly(vinyl chloride) were doped by nanomaterials of CuO and CoO with various concentration ratios has been applied on a glass substrate. The result obtained was shown the thin film coating of CuO and CoO has a high absorptive of solar energy. Optical properties have been measure by the UV-Visible spectra and reflectivity tests in the wavelengths range (200-1200 nm) at room temperature. The transmittance, absorbance, refractive index, extinction factor, and energy gap were used to study different optical properties. Optical energy gap (Eg), absorbance coefficient, reflectance, transmittance, skin depth, optical density. These properties have been increased by doping PVC with nanomaterials. The energy gaps were calculated and their values have been investigated. The energy gap value was found to be a decline from 5.15 eV for pure PVC to 2.2 and 2.1 eV for PVC/CuO and PVC/CoO, respectively of the nanocomposites. The optical data was interpreted and analyzed by phonon theory to assist in the direct transition of electrons, it is clear that the energy gap is influenced by nanomaterials used in doping poly(vinyl chloride), then the present results depend on the optical properties of pure and poly(vinyl chloride) films adopted with nanomaterials. The AFM has been used to determine the surface morphology of the thin films and the distribution of nanoparticles which was inspected in three dimensional images.
