摘要：
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.
