摘要:由于强相干及大比表面效应,纳米材料在光学、热学、电学、磁学、力学以及化学方
面表现出优异特性。表面改性是克服其团聚、增强其相容性,使纳米材料在介质中达到纳米
级分散,从而在应用过程中发挥特性的有效途径。在众多表面改性方法中,可逆加成-断裂
链转移自由基(RAFT)接枝聚合能够在表面引入多种功能性聚合物,且聚合物的分子量和
微观序列结构可设计调节,相对其它方法具有极强的适应性。本文介绍了 RAFT 表面接枝聚
合的一般策略,综述了近年来 RAFT 接枝聚合在纳米材料接枝功能性聚合物刷的研究进展。

Abstract: Abstract: Due to the strong coherence and large specific surface effect, nanomaterials
have showed excellent properties in optical, thermal, electrical, ic, mechanical and
chemical aspects. Surface modification is an effective way to e its aggregation, enhance
patibility and dispersion in the application process. Among surface modification methods,
reversible addition fragmentation chain transfer (RAFT) graft polymerization has exhibited
stronger adaptability in grafting a variety of functional polymers on the surface, and controlling
the molecular weight and structures of the polymer. The general strategies of RAFT surface
grafting polymerization were described in this paper, and the application of the RAFT grafting
polymerization in grafting function
