چکیده
|
Graphene, polyaniline and graphene nanosheets(GNS)/polyaniline(PANI) nanocomposite are
fabricated on steel by constant current electrochemical method in aniline monomer and SDS
surfactant.The characterization of synthesized catalysts have been investigation by FT-IR,SEM
techniques.The GNS/PANI composites exhibit better electrochemical performances than the pure
individual components. A remarkable specific capacitance of 1100 F g−1 (based on GNS/PANI
composites) is obtained at a scan rate of 5 mV s−1 in 0.5 M H2SO4 solution compared to 380 F
g−1 for pure PANI and 200 F g−1 for GNS. The excellent performance is not only due to the
GNS which can provide good electrical conductivity and high specific surface area. The resulting
composites are promising electrode materials for high-performance electrical energy storage
