采用电化学原位聚合可控地合成了聚苯胺(PANI)/活性碳纤维毡(ACC)复合材料电极,用 FT-IR、SEM和电化学方法对复合材料电极的结构、形貌和电化学性能进行了表征,结果表明,ACC 上的酸性(含氧)官能团与碱性苯胺通过静电和氢键相互作用,对聚苯胺的成核起到诱导作用；通过调控电解质浓度、电流密度和施加电流方式可有效制备出不同形貌、不同电化学性能的PANI/ACC有序结构复合材料；该复合材料呈现出 ACC 双电层电容和 PANI 法拉第赝电容的协同效应,在充放电电流为1A/g时,复合材料比电容达362 F/g,为同等条件下ACC的2.5倍,该复合材料不仅电化学活性优异、成本低、具有快速地充放电性能,且该制备工艺过程简单,易于大规模工业化生产。

Activated carbon fiber cloths (ACC)/polyaniline (PANI)composites with ordered structure were con-trollable prepared by electrochemical polymerization.The morphology,structure and electrochemical perform-ance 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 1 A/g reached 362 F/g,which was 2.5 times 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.
