摘　　要：辐射引发膜接枝有射线穿透力强、反应均匀、操作简单、无需添加引发剂、应用广泛等优点。通过改变辐照方式(共辐射、预辐射)、辐射剂量、剂量率、气氛(氧气、真空、充氮等)、基材、单体等因素,可以有效控制接枝链的长短和分布。文中综述了γ-射线共辐射法和预辐射法的机理、主要影响因素(包括辐射剂量、剂量率、氧气、基材、单体、添加剂等),以及在制备环境响应膜、抗菌膜、抗污染膜、生物医用膜等功能膜方面的最新研究进展。Radiation-induced grafting is one of the most important methods in the surface modification. Radiationinduced grafting of membranes received great attention because of its high penetration, easily operation, free initiator and wide-spread applications. The length and distribution of the grafting chains can be controlled by changing the irradiation pattern （simultaneous irradiation and pre-irradiation）, irradiation dose, dose rate, atmosphere （oxygen, vaccum, nitrogen）, base membrane and monomer. The recent advances in radiation grafting of membranes were reviewed. The mechanisms of simultaneous irradiation and pre-irradiation, affecting factors such as dose, dose rate, oxygen, polymer, monomer and additive, and main applications in the preparation of environmental response, antibacterium, anti-pollution and biomedical membranes were also introduced.
