Abstract

Abstract: A novel simple and efficient route was carried out for preparation of dual responsive gold nanoparticles based on click chemistry and reversible addition-fragmentation chain transfer(RAFT) polymerization. The functionalized hybrid gold nanoparticles were characterized by FTIR, XPS, TEM and TGA methods. The results indicate that the hybrid gold nanoparticles are dispersed well. The surface grafting density of hybrid nanoparticles are calculated to be about 0.6 Chains/nm2. In addition, the hybrid gold nanoparticles show dual responsive phenomenon as the temperature or pH value changed. It is demonstrated that the route of preparation of hybrid gold nanoparticles was simplified controlled and functionalized using click chemistry/RAFT polymerization method.

Key words: Click chemistry, RAFT polymerization, Gold nanoparticle
