摘要：The graphene-Ag2O/polyaniline (GAP) composite has been synthesized by in-situ polymerization. It has been observed that Ag2O nanoparticles exist on the porous spongy background of PANI (polyaniline). The optimized composition of the synthesized composite exhibits an extraordinary specific capacitance of 1572 Fg(-1) at 0.05 Ag-1 current density and good cyclic stability of 85% over 3000 charge-discharge cycles. The extraordinary electrochemical performance indicates the positive synergistic effect of PANI, graphene and Ag2O. The Ag2O nanoparticles might be responsible for improved electrical conductivity, and graphene might contribute in enhancing the electrochemical stability of the PANI electrode.
