| 摘 要： | 利用阶跃电位、循环伏安等电化学方法，应用金属电沉积理论,研究聚苯胺纳米管在阳极氧化铝模板（AAO）内电聚合的生长机理.结果表明：电聚合初始，苯胺二维非扩散控制的瞬时成核生长形成聚苯胺晶胞链段单层,单层形成以后，聚苯胺的生长过程变为线性扩散控制. XRD实验进一步证实电聚合的聚苯胺同时包含结晶相和无定型相结构.

| Abstract: | According to the theory on eletrocystallization of metal, the growth mechanism of polyaniline nanotubules in alumina template was studied by electrochemical methods, such as chronoamperometry,cyclic voltammetry. It was found that a chain monolayer of polyaniline crystal cell was formed by the two dimensional instantaneous nucleation growth without diffusion control during the initial stage of eletropolymerization, and after forming the monolayer, the growing process of polyaniline tubules was controlled by diffusion instead. The results of XRD showed that the eletrosynthesized polyaniline structure is composed of both the crystalline phase and the amorphous phase,consistent with the electrochemical experiment results. Meanwhile, it is possible that the cystallization of polymer can be studied by electrochemical methods with the theory on eletrocystalization of metal. |
