Effect of ZnO Filler on Structural and Optical Properties of Polyaniline-ZnO Nanocomposites

PANI based nanocomposite filled with ZnO nanoparticles was prepared by chemical synthesis method. Aniline hydrochloride with ammonium persulphate was used as oxidant. The structural investigation of prepared nanocomposite was carried out by X-ray diffraction technique (XRD). XRD pattern confirmed the Wurtzite structure of ZnO nanoparticles. The UV- Vis spectra of PANI-ZnO nanocomposite was studied to investigate the optical behavior after doping ZnO nanoparticles in to the polymer matrix. The addition of ZnO nanoparticles gives to the red shift of π-π⁎ transition of PANI. Chemical bond and stretching vibrations assigned to different peaks were evaluated by FTIR spectra.
