RAFT法在纳米粒子表面改性中的最新进展

摘要

Surface-modification of nanoparticles is of great importance due to surface atoms and certain toxicity in biology. The RAFT (reversible addition-fragmentation chain transfer) polymerization technique has proved to be a versatile tool to modify the nanoparticles surface with a variety of functional polymers. The latest research progress of modifying Au、SiO2 and Fe3O4 nanoparticles by RAFT polymerization are briefly reviewed in this paper.%纳米粒子表面原子很活泼,易与其他原子结合且在生物体内有一定的毒性,因此需要改善纳米粒子表面的性能.随着可逆加成-断裂转移(reversible addition-fragmentation chain transfer,RAFT)聚合机理和技术不断地完善,该聚合法为纳米粒子表面接枝功能性聚合物提供了一条有效的途径.文中综述了RAFT法在金、二氧化硅以及四氧化三铁纳米粒子表面改性中的最新研究进展.
