Polyaniline(PANI) was coated on the surface of reduced graphene oxide(RGO) through in situ chemical oxidation polymerization of aniline(ANI) monomers in the presence of graphene suspension in HCl solution. High electrochemical performance of the PANI-RGO electrode could be due to increasing active sites for the deposition of polyaniline provided by large surface areas of graphene nanosheets and the synergistic effect between polyaniline and graphene oxide. These results demonstrated the importance and great potential of graphene oxide in the development of high-performance supercapacitor based on polyaniline. The morphology, structure and crystallinity of the composites were examined by Fourier-transform infrared spectroscopy(FTIR), scanning electron microscopy(SEM), transition electron microscopy(TEM) and X-ray diffraction(XRD). Electrochemical properties were characterized by cyclic voltammetry(CV)in 1M H2SO4 electrolyte. |
