摘　　要：表面引发原子转移自由基聚合(SI-ATRP)是在材料表面获得可控聚合物刷的一种有效方法。根据膜分离的对象,通过SI-ATRP法引入不同的活化基团,使膜表面"活化",可设计出具有新型结构及性能的分离膜。综述了SI-ATRP技术的特点,介绍了近年来SI-ATRP在膜表面亲/疏水改性、生物相容性及膜制备上的应用,最后对其研究前景作了展望。Surface-initiated atom transfer radical polymerization （SI-ATRP） is one of the ＂grafting form＂ techniques, which has been widely used in modification of material surface. Using this method, the well-defined polymer brushes can be grafted onto various surfaces. Graft polymer on the membrane surface via SI-ATRP, we can effectively change the composition of the polymer brushes and the degree of polymerization, and then change the nature of the membrane surface. This article summarized the characteristics of SI-ATRP and application of SI-ATRP in surface graft modification for different membranes, such as pervaporation membrane, molecularly imprinted membrane, gas separation membrane. Finally, it described its research prospect.
