Polyaniline (PANI) has been extensively studied because of its cost-effective, good environmental stability, redox reversibility, and facile synthesis procedure. In this work, Polyaniline (PANI)/graphene nanosheets (GNS) composite were prepared by a chemical oxidation polymerization. The morphology, structure and crystallinity of the composites were examined by SEM, TEM and XRD. Electrochemical properties were characterized by Cyclic Voltammetry. It exhibited the better specific capacitance than the pure individual components. The introduction of PANI and GNS highly improves the electrochemical performance because GNS not only serve as supporting materials, but also provide a large number of active sites. The improved properties of composites demonstrated a promising materials for supercapacitor electrodes materials. |
