采用电化学聚合法制备了有序结构的活性碳纤维布(ACC)/聚苯胺(PANI)复合材料。用扫描电子显微镜、傅立叶变换红外光谱(FT-IR)和电化学方法分别对复合材料的形貌、结构和电化学性能进行了表征。结果表明，苯胺单体是通过苯胺与ACC表面含氧基团之间的氢键和静电作用力自发吸附在ACC上的。具有有序结构的复合材料兼具双电层电容器和法拉第伪电容的特性，在电流密度为1a/g时，比电容达到362F/g，是相同条件下ACC的2.5倍，具有良好的电化学活性和低成本，工艺简单，适合工业化生产。
Activated carbon fiber cloths(ACC)/polyaniline(PANI)composites with ordered structure were controllable prepared by electrochemical polymerization.The morphology,structure and electrochemical performance of the composites were characterized by SEM,FT-IR and electrochemical method,respectively.It was shown that aniline monomers were spontaneously adsorbed onto ACC by hydrogen bond and electrostatic force interaction between aniline and oxygen-containing groups on the ACC surface.The aniline monomers adsorbed on the ACC were electro-polymerized along the surface when electrochemical reaction was initiated;the PANI with different morphologies was obtained by changing electrolyte,current density and current applied method;The composite with ordered structure exhibits the double-layer capacitor as well as Faraday pseudocapacitor characteristics.The specific capacitance of the composites at a current density of 1A/g reached 362F/g,which was 2.5times of the ACC at the same condition.The product showed a good electrochemical activity and low cost.The technological process was simple and suitable for industrial production.
