The middle peak which appeared frequently on the voltammetric curves has been interpreted as the degradation of the polymer, according to the results of anion effect. When α-CD (α-cyclodextrin) was added in the acidic solution of aniline to form aniline-α-CD complex, the middle peak became even higher during electrochemical polymorization. This suggests that the middle peak is mot originated from cross-link or ortho-polymerization in aqueous acidic solution.
