In this study, we prepared Graphene Nanosheet and polypyrrole composite (PPy/GNS) is synthesized via in situ polymerization of pyrrole monomer in the presence of graphene under acid conditions. The structure and morphology of the composite are characterized by X-ray diffraction (XRD), Fourier transform infrared spectrometer (FTIR), scanning electron microscopy (SEM) and transmission electron microscope (TEM). Electrochemical properties were characterized by cyclic voltammetry (CV) in 1M NaNO3 electrolyte. The nanostructure of the PPy was induced and greatly affected by the addition of graphene during the synthesis process, which might greatly contribute to the electrochemical properties of the composite. The composite is a promising candidate for supercapacitors to have higher specific capacitance, better rate capability and cycling stability than those of pure polypyrrole. |
