Abstract: The Electrochemical (galvanostatic) study of polypyrrole/Zinc oxide film synthesized with various dopant like potassium chromate (K2CrO4), potassium dichromate (K2Cr2O7) And potassium permanganate (KMnO4) has been carried out. The electrochemically synthesized (Ppy/ZnO) films were characterized by electro- chemical technique, UV-visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) and four probe technique for conductivity measurement. This comparative Study observed that as compare to (PPy/ZnO/K2CrO4), (PPy/ZnO/K2Cr2O7) And (PPy/ZnO/KMnO4) film but the (PPy/ZnO/KMnO4) film provide a polymer matrix having a good porosity, high conductivity, uniform surface morphology and good mechanical and environmental stability. This is suitable for Immobilizations of biocomponant.
