▎ 摘  要

We fabricated continuouswrinkle-structured graphene film electrodes by a wet-spinningmethod. The assembled supercapacitors showed an excellent rate performance (79% retention from 1 to 100 A g(-1)) with a high specific capacitance (177 F g(-1) at 1 A g(-1)). When further functionalized with polyaniline, the electrodes maintained their wrinkled structure and showed an improved rate capability (90% retention from 1 to100 A g(-1)) with a superior capacitance as high as 505 F g(-1) (1 A g(-1)).
