Abstract

This research article refers to the synthesis and characterization of MnO2 nanoparticles embedded on polypyrrole nanotubes. The product was synthesised by chemical oxidative polymerization method. Combination of MnO2 nanoparticles and polypyrrole nanotubes enhance the capability of the nanocomposite. The microstructures and properties of Polypyrrole nanotubes (PPy) and MnO2 embedded Polypyrrole nanotubes (PPy:MnO2) were determined by TEM and SEM. FT-IR spectra was recorded to determine the chemical structure of the products. XRD was used to determine the crystalline structure of the products. The PPy:MnO2 nanocomposite electrode shows substantial improvement in the redox performance compared to individual component PPy. The specific capacitance value of electrode material PPy:MnO2 was found to be ~200 F g−1 at 5 mV s−1.
