    PANI-ZnO nano composite was synthesized by both electrochemical and chemical synthesis methods. Chemically synthesized nanomaterials were prepared via in-situ oxidation polymerization method. Then, the synthesized nanomaterial’s: Polyaniline (PANI), ZnO and PANI-ZnO were characterized by Ultraviolet- Visible (UV-Vis), SEM and Fourier Transform Infrared spectroscopy (FT-IR). The UV-Vis spectrum of PANI-ZnO nano composite was studied to investigate the optical properties. After addition of ZnO particle to the PANI, the polymer shows red shift of π to π* transition. The Scanning Electron Microscope (SEM) shows PANI nano fibers distributed on the surface of ZnO. Moreover, Fourier Transform Infrared spectroscopy (FT-IR) spectra show that chemical bond and stretching assigned to different peaks.
