▎ 摘　　要

Three dye-functionalized graphene oxide/polyaniline (GAP) composites were first prepared by optimizing acid blue 74 (AB74) feed content, and then dye-functionalized graphene/polyaniline (rGAP) nanocomposites were obtained from the GAP composites through reducing and re-protonating treatments. The AB74 dye molecules with negatively charged sulfonic groups can effectively prevent aggregation of graphene sheets during the reduction process of graphene oxide, and can be used as a bridge to attach polyaniline nanorods via pi-pi conjunction and electrostatic attraction. Furthermore, when rGAP5 (the AB74 feed content of 5 wt.%) was used as a supercapacitor electrode material, it achieved a high specific capacitance of 579 F g(-1) at a current density of 0.5 A g(-1), good cycling stability and rate capacity.
