A schematic diagram to reveal the effects from various initial molar ratios of [AN]:[APS]:[HCl] on the polymerization of aniline (AN) is proposed with [APS]/[AN]=0.23 at [AN]=0.27 M. For [AN]=[HCl], the initial solution has a richness of neutral ANs. The as-obtained samples have features of phenazine-like oligomers. For [AN]<[HCl], neutral ANs are almost protonated to become anilinium cations. The as-obtained samples possess features of polyaniline. Finally, the formation mechanisms for polymerization of AN into various forms of nanostructures were discussed.
