摘　　要：原子转移自由基聚合(ATRP)对膜的亲水化/功能化改性包括对膜基体材料的共聚改性和对膜的表面改性。膜基体材料的改性最多见于PVDF为主链的两亲性聚合物。ATRP对膜的表面改性尤其是膜的表面引发方法,可实现将不同功能性单体接枝到聚合物膜表面,得到了抗污染能力强,生物相容性好,开关响应迅速等多种功能性表面层。直接的表面引发改性是一种高效,灵活的表面修饰/功能化方法,也是目前应用最广泛的改性技术。Membranes＇ hydrophilic and functionalization modification with Atom transfer radical polymerization （ATRP） technique included the matrix polymers＇ ATRP copolymerization and surface modification. The matrix polymers＇ modification was mostly seen in amphiphilic copolymers with PVDF as backbones. And the membranes surface modification with ATRP method, especially the surface-initiated method had been successfully grafted various functional monomers to the membranes＇ surface,obtaining functional surface with strong fouling-resistance,nice biological incompatibility and smart responsive-switch top layers. This direct surface-initiated method is now the most widely adopted and considered as an effective and flexible surface embellishment/functional strategy.
