Interpolymer complexation of water-soluble self-doped polyaniline

Water-soluble polyaniline compounds are important for potential applications in organic electronics. The use of organic inks as an example require accurate control of the size and charge of the conducting particles, which both can be optimized with an additional complexation, charge neutralization....

Description
Summary:Water-soluble polyaniline compounds are important for potential applications in organic electronics. The use of organic inks as an example require accurate control of the size and charge of the conducting particles, which both can be optimized with an additional complexation, charge neutralization. We report here the synthesis and characterization of internally doped highly sulfonated polyaniline with sulfur to nitrogen ratio S/N of ∼1. This electroactive polyelectrolyte, which has high water solubility in all pH regions, was complexed with oppositely charged poly- N-ethyl-4-vinylpyridinium bromide and the properties of such interpolymer complex were studied.
