An attempt has been made to investigate the effect of SiO2 nanoparticles on the conductivity of polypyrrole conducting polymeric films prepared by an electrochemical method. The obtained nanocomposites were characterized by FTIR, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and scanning electron microscopy (SEM). The results indicate that the conductivity of the nanocomposite was significantly increased in comparison to pure polypyrrole. Fitting the impedance results to an equivalent circuit reveals that addition of SiO2 nanoparticles reduces the ohmic resistance due to the better conductivity.
