Abstract: 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.

Key words: electrochemical polymerization method, aligned-multi walled carbon nanotubes, polyaniline nanowires array
