The study involves the synthesis of PPy and PPy loaded with various metal oxides TiO2, WO3, Fe2O3, and SnO2 with different ratios by polymerization procedure. The UV-Visible analysis was carried in the wavelength range (300-1100nm) to determine the optical parameters like optical energy gap and optical constants. From the analysis of absorption spectra, the band gaps of polypyrrole undoped are 1.85eV While the samples of PPy/SnO2 composite gained the highest values 2.2eV at weight Percentage (5%) but with PPy/Fe2O3 gained lowest values 1.5eV at weight Percentage (1%).
