Fabrication of high-performance supercapacitors with exceptional mechanical flexibility and durability for wearable electronics still remains an elusive challenge. In this paper, oriented polyaniline (PANI) nanowires were in-situ polymerized on a reduced graphene oxide (rGO)/poly(3,4-ethylenedioxythiophene) (PEDOT)/polypropylene (PP) fabric to produce highly robust flexible electrodes for high-performance supercapacitor. The obtained binder-free PANI/rGO/PEDOT/PP electrode fulfills an outstanding electrochemical performance with a specific capacitance (C_s) of 572.7 mF/cm² and excellent retention of 97.4% over 5000 cycles. More significantly, the corresponding symmetrical supercapacitors could achieve a high C_s of 432.1 mF/cm² and a satisfactory energy density of 49.6 μWh/cm². In addition, this device exhibits very stable capacitance properties with the Cs retention of 95.3% and 92.9% under mechanical bending and folding over 1000 times, respectively. All these results indicate a remarkably enhanced electrochemical performance, which provided a valuable reference for the development of flexible supercapacitor electrodes.

为可穿戴电子设备制造具有卓越机械灵活性和耐用性的高性能超级电容器仍然是一个难以捉摸的挑战。在本文中，定向聚苯胺（PANI）纳米线在还原氧化石墨烯（rGO）/聚（3,4-乙撑二氧噻吩）（PEDOT）/聚丙烯（PP）织物上原位聚合，以生产高度坚固的柔性电极，用于高性能超级电容器。获得的无粘合剂PANI/rGO/PEDOT/PP电极具有出色的电化学性能，比电容（C _s）为572.7 mF/cm ²，5000次循环后保持率高达97.4%。更重要的是，相应的对称超级电容器可以实现432.1 mF/cm的高C _s²和令人满意的能量密度为 49.6 μWh/cm ²。此外，该器件表现出非常稳定的电容特性，在机械弯曲和折叠超过 1000 次的情况下，C s 保留率分别为 95.3% 和 92.9%。所有这些结果表明电化学性能显着提高，为柔性超级电容器电极的开发提供了有价值的参考。
