The silver nanowire (AgNWs) / cotton fiber was used as a conductive substrate with high conductivity charge transfer. Then the polyaniline (PANI) molecular chain was fixed on the AgNWs / cotton fiber by in-situ polymerization to prevent its dedoping and improve its cyclic properties. Thus the flexible capacitor electrode material with conductive, specific capacity and cyclic properties was obtained. The results showed that when the mass ratio of KH-560 to AgNWs/cotton fiber was 3:1, the grafting rate of epoxide group on the modified AgNWs/cotton fiber was the highest. When the mass ratio of aniline to modified AgNWs cotton fabric was 3:1, the PANI content of in-situ polymerization on the fabric surface was the highest, 20.83%. The specific capacity of PANI/AgNWs/cotton fiber electrode material was the highest, 154 F/g, after 5000 cycles of charging and discharging, the specific capacity could keep 96%. It is worth mentioning, the introduction of PANI and AgNWs could significantly improve the wear resistance of cotton fiber, the friction resistance of the cotton fabric increased to 36,000 times. It is provided a new idea for design a flexible capacitor electrode material integrating electrical conductivity and cyclic stability.

银纳米线（AgNWs）/棉纤维用作具有高导电性电荷转移的导电基材。然后通过原位聚合将聚苯胺（PANI）分子链固定在AgNWs/棉纤维上，以防止其去掺杂并改善其循环性能。从而获得具有导电、比容量和循环特性的柔性电容器电极材料。结果表明，当KH-560与AgNWs/棉纤维的质量比为3:1时，改性AgNWs/棉纤维上环氧基的接枝率最高。当苯胺与改性AgNWs棉织物的质量比为3:1时，织物表面原位聚合的PANI含量最高，为20.83%。PANI/AgNWs/棉纤维电极材料的比容量最高，154 F/g，经过5000次充放电循环后，比容量可保持96%。值得一提的是，PANI和AgNWs的引入可以显着提高棉纤维的耐磨性，棉织物的摩擦阻力提高到36000倍。为设计集导电性和循环稳定性于一体的柔性电容器电极材料提供了新思路。
