Abstract

We report the design and preparation of graphene and polyaniline (PANI) woven-fabric composite films by in situ electropolymerization. The introduction of PANI greatly improves the electrochemical properties of solid-state supercapacitors which possess capacitances as high as 23 mF cm(-2), and exhibit excellent cycling stability with ∼ 100% capacitance retention after 2000 cycles. The devices have displayed superior flexibility with improved areal specific capacitances to 118% during deformation.

摘要

我们报道了通过原位电聚合制备石墨烯和聚苯胺（PANI）织物复合薄膜的设计与制备方法。聚苯胺的引入极大地改善了固态超级电容器的电化学性能，该超级电容器具有高达23 mF cm(-2)的电容，并表现出优异的循环稳定性，在2000次循环后电容保持率约为100%。这些器件在变形过程中表现出卓越的柔韧性，面积比电容提高到了118%。
