以有序碳纳米管阵列电极为基底电极，在硫酸或高氯酸溶液中，分别探明不同电化学聚合方法以及苯胺单体浓度对聚苯胺形貌的影响. 结果表明：采用循环伏安法无法制备出聚苯胺纳米线；而应用恒电位法虽可制得聚苯胺纳米线，但纳米线不能形成有序阵列；只有应用恒电流方法，并且以高浓度苯胺的高氯酸溶液作为聚合溶液，方能制得有序聚苯胺纳米线阵列.

The effects of electrochemical fabrication methods in different aniline concentrations on the morphologies of polyaniline, which was polymerized on the aligned-multi-walled carbon nanotubes electrode in H2SO4 or HClO4 electrolyte solution, were investigated. It was demonstrated that the polyaniline nanowires would not be prepared by cyclic voltammotry, whereas the nanowires could be obtained by the potentiostatic method without forming the ordered array. Only when the aniline concentration in HClO4 solution was high enough, the ordered polyaniline nanowires array could be fabricated by the constant current method.
