Polymerization of Aniline by Auric Acid: Formation of Gold Decorated Polyaniline Nanoballs

Abstract

Abstract Summary: We report a new method for the preparation of polyaniline nanoballs by using HAuCl 4 as an oxidizing agent. During the reaction, aniline is oxidized and forms polyaniline whilst the hydrogen tetrachloroaurate is reduced and forms gold nanoparticles. These gold nanoparticles are found to decorate the nanoballs. The resultant precipitate and corresponding TEM image of the gold‐nanoparticle covered polyaniline nanoball. magnified image The resultant precipitate and corresponding TEM image of the gold‐nanoparticle covered polyaniline nanoball.
