本研究通过原位电化学聚合/降解工艺合成了柔性单壁碳纳米管/聚苯胺（SWNT/PANi）复合薄膜。循环伏安（CV）测试表明，独立的SWNT/PANi复合膜除了具有良好的柔韧性和重量外，还具有良好的电化学性能。在电降解前，经过90次电化学聚合，SWNT/PANi复合膜的比电容最高，为501.8 F/g。电降解后，它达到706.7 F/g，增加了约40%，这是由于更多可用的电荷转移通道和由脱落的无序聚苯胺溶解产生的多晶聚苯胺区域增加。
In this work, flexible single-walled carbon nanotube/polyaniline (SWNT/PANi) composite films have been synthesized through an in situ electrochemical polymerization/degradation process. In addition to their good flexibility and light weight, cyclic voltammetry (CV) tests revealed that free-standing SWNT/PANi composite films also showed good electrochemical properties. Before electrodegradation, the highest specific capacitance, 501.8 F/g, was obtained for SWNT/PANi composite films with 90 electrochemical polymerization cycles. It reached values up to 706.7 F/g after electrodegradation, an increase of ∼40%, which was attributed to more available charge-transfer channels and increased polycrystalline PANi regions that were produced by the dissolution of off-lying disordered PANi.
