摘要由于聚苯胺（PANI）独特的质子酸掺杂机制，当在高pH值（一般PH>4）溶液中会发生去质子化过程，导致电化学活性降低，为解决PANI在中性溶液中的“失活”问题，本文采用超声混合法、乳液聚合法、电化学聚合法制备了聚苯胺/碳纳米管（PANI/CNT）、聚苯胺/富勒烯(PANI/C60)复合膜。用循环伏安法(CV)对复合膜在酸性和中性溶液中的电化学活性进行了测试，并将其与纯的聚苯胺在酸性和中性溶液中的测试结果作了对比，发现用超声混合法制备的PANI/CNT复合膜对提高聚苯胺在中性溶液中的电化学活性效果最明显。63614

Title  Investigation of electrochemical activity of polyaniline electrodes doped with carbon nanotube

Abstract Generally, the deprotonation process based on unique protonic acid doping mechanism will result in the loss of conductivity and electroactivity in neutral or alkaline solutions with high pH values. Much effort had been exerted in the development of approaches to overcome this issue. In this work, we used three methods named ultrasonic mixing, emulsion polymerization and electrochemical polymerization to prepare the polyaniline/carbon nanotube (PANI/CNT) and the polyaniline/fullerene (PANI/C60) composite films.The electrochemical activity of films had been characterized using cyclic voltammetry in acidic or neutral solution . When compared with that of pristine PANI, it showed that the PANI/CNT compsite film prepared from ultrasonic mixing method has better electrochemical activity in neutral solution.
