Polypyridine and their composites are attractive materials for the use in existing and emerging technologies because of their light weight and low cost. In the present paper, I focused on the structural properties of Cu-doped polypyridine polyvinyl acetate supported composite films, wherein polyvinyl acetate (PVAc) as the host matrix. Polypyridine-PVAc composite thin films were synthesized by chemical oxidative polymerization method with the solvent methanol and Copper chloride (CuCl) as an oxidant as well as dopant. All films were characterized using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared (FTIR) spectroscopy. 
X-RD spectra shows the sharp peaks in all prepared samples represents the crystalline nature of material, which is due the phases of polypyridine and CuCl (JCPDS data file No. 01-077-2383). Crystalline nature of the material is seen from the scanning electron micrographs which also reflected in the XRD spectra. The IR spectra of all samples shows peaks at 1444.72, 1437.17 and 1456.27 cm^-1 and second peak at 1595.38, 1595.87 and 1595.09 cm^-1 may assigned to typical polypyridine ring vibration.
