摘要

采用电化学循环伏安法

在柔性石墨纸基底材料上合成了聚苯胺/活性炭(PANI/AC)复合薄膜。通过SEM观察了不同扫描圈数下复合薄膜的表面形貌

通过循环伏安(CV)、交流阻抗(EIS)、恒流充放电等电化学测试方法

研究了聚苯胺/活性炭复合电极的电性能。由SEM图谱可知

不同扫描圈数下

聚苯胺/活性炭的形态也有所不同

电化学测试结果表明

以柔性石墨纸为基底材料

扫描圈数在3圈时

不仅比容量较高

达504 F·g-1

而且循环稳定性较好

经2000次循环后

容量衰减仅为初始容量的14%。

Abstract

Cyclic voltammetry was used to deposite polyaniline/activated carbon(PANI/AC)film on flexible graphite paper.The surface morphology of the PANI/AC film was characterized by SEM

and the electrochemical properties of PANI/AC film electrode were investigated by cyclic voltammetry(CV)

electrochemical impedance spectroscopy(EIS)and galvanostatic charge-discharge.From SEM graphs

PANI/AC film had different forms with increasing scan cycles

and from electrochemical measuring results

PANI/AC electrode synthesized by three scan cycles had the best electrochemical performance among those different scan cycles electrodes.Specific capacitance was about 504 F穏-1

and only about 14% of the initial capacitance was lost after 2000 cycles in circling life process.
