文摘

Electrochemical technique, in situ atomic force and electron microscopies, and X-ray analysis were used for the determination of the mechanism of poly(o-methoxyaniline) nanostructures electrochemical formation. The electrochemical process of nanostructures growth was carried out on a membrane template, which back side was evaporated with platinum. The presence of the metal film on the wall of the membrane pores has been detected. On this basis the mechanism of simultaneous growth of nanostructure on the pore wall and on its bottom in the contradiction to the view that fibrils or nanotubes grow from the bottom to the top of the pores is proposed. The results obtained using the TM-AFM technique indicate that only limited number of the pores are available for the nanostructures formation.
