Synthesis of polyaniline-gold nanocomposites using 'grafting from' approach

摘要

Polyaniline-gold nanocomposites containing polyaniline nano-structures attached to well-dispersed uniform-size gold nano-particles were obtained using a surface initiation approach.Polyaniline nanostructures have recently been the focus of intense study due to their potential applications in sensing and catalysis.Different aroups have shown that sensors based on polyaniline nanofibers have a faster response time compared to bulk polyaniline.This advantage is primarily due to their high surface areas.Hybrid systems consisting of inorganic nanoparticles with p-conjugated polymers as supporting matrices have interesting properties,particularly for dielectrics,energy storage,catalytic activity,and magnetic susceptibility.
