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.
