摘　　要：介绍了一些主要的可控/活性自由基聚合法,包括氮氧调解自由基聚合法(NMRP)、原子转移自由基聚合法(ATRP)、可逆加成断裂链转移聚合法(RAFT)在粒子表面接枝聚合形成无机纳米粒子/聚合物的壳核结构,达到了对粒子改性的目的。并提出了一些目前研究中存在的问题,对可控/活性聚合应用的发展进行了展望。Several controlled/living radical polymerization methods were mainly introduced , including nitroxide-mediated radical polymerization（NMRP）, atom transfer radical polymerization（ATRP） and reversible addition-fragmentation chain transfer polymerization （RAFT）, in the application of inorganic nano-particles surface-initiated polymerization. The structure of inorganic core/polymer shell was formed, and achieved the aim of surface modification. Moreover, some existed problems in recent years were suggested, and further development of the application of controlled/living radical polymerization was looked forwards.
