Polyaniline stabilized highly dispersed gold nanoparticle : an in-situ chemical synthesis route

In this communication, we describe a simple and in-situ route for the synthesis of polyaniline-gold thin composite film by using aniline and auric acid as the precursors. The average sizes of the resulting gold nanoparticles are 6-7 nm, which are dispersed in the polyaniline film. During the synthes...

Description
Summary:In this communication, we describe a simple and in-situ route for the synthesis of polyaniline-gold thin composite film by using aniline and auric acid as the precursors. The average sizes of the resulting gold nanoparticles are 6-7 nm, which are dispersed in the polyaniline film. During the synthesis AuCl4(-) behaves as an oxidizing agent causing the conversion of aniline to polyaniline and reduction of AuCl4(-) leads to gold nanoparticles that are stabilized by the polymer matrix.
