Polyaniline/Gold Nanoparticle Composites

Polyaniline/gold nanoparticle composites not only retain the original especial performance of polyaniline and gold nanoparticle respectively, but also exhibit coadjutant effect that is beneficial for improving the properties of polyaniline matrix in composites. The polyaniline/gold nanoparticle composites have been intensively studied in recent years due to their unique properties including outstanding intrinsically electrical conductivity, excellent reactive catalysis and especial behavior of charge transfer. In this paper, the recent developments of polyaniline/gold nanoparticle composites are reviewed, and the preparation methods and mechanisms are summarized. The applications of the composites are briefly introduced in aspects of biomedicine, sensors and microelectronic devices. Finally, the prospect of the future research is proposed. Contents
