Directional assembly of polyaniline functionalized gold nanoparticles

Abstract

Polyaniline encapsulated and functionalized self-assembled gold nanoparticles have been synthesized using an interfacial polymerization approach. The polyaniline and gold nanoparticles were formed at the aqueous and organic interface and a directional growth of the self-assembled gold nanoparticles was observed. The resultant composite material was characterized by means of different techniques. IR, Raman and UV–visible (UV–vis) spectra provided information on the chemical structure of the polymer. UV–vis spectrum also indicated the functionalization of the gold nanoparticles by the polymer. TEM images showed the morphology of the polymer and the metal particles.
