▎ 摘　　要

Graphene/polyaniline composites (GP) were prepared from aniline and graphite oxide using an electrochemical method. The structure characterization and surface morphology were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS), and its electrochemical properties were measured. The results show that the composite keeps the basic morphology of graphene and that the polyaniline particles are uniformly dispersed. The specific capacitances of the composite materials reach 352 and 315 F . g(-1) at 500 and 1000 mA . g(-1), respectively, higher than those of graphene and polyaniline. The majority (90%) of the capacitance remains after 1000 cycles of charge and recharge at 1000 mA . g(-1). The composite shows potential for use in supercapacitors.
