Multilayer growth of conductive polyaniline: A two-pot, alternate, oxidation and reduction strategy

Thin films of polyaniline (PAn)-oligomers were gradually converted into thick conductive PAn films using a two-pot, alternate oxidation and reduction strategy. The well known redox mechanism of aniline polymerization was used to design independent oxidation and reduction processes. An important aspect of the strategy is the recyclable nature of raw materials, aniline and oxidant in the pot. Using appropriate dopants, well-defined PAn nanostructures were generated.
