文章介绍了表面光接枝聚合技术的原理、接枝方法及影响分离膜表面光接枝聚合的因素,如溶剂类型,光敏剂种类及浓度,基膜与单体等。简要阐述了表面光接枝在分离膜上的应用进展,包括合成耐生物污染膜、具有分子识别功能的膜、环境敏感性膜及表面固定化的膜,固定化试剂包括生物试剂、吸附试剂、催化试剂等。 In this paper, the principle, grafting method and the factors affecting the surface grafting of the surface of the separation membrane are introduced, such as the type of solvent, the type and concentration of photosensitizer, the base membrane and monomers. The application progress of grafting surface light onto the separation membrane is briefly described, including the synthesis of biofilm, membrane with molecular recognition, environmental sensitive membrane and membrane with immobilized surface. Immobilized reagents include biological reagent, adsorption reagent, catalysis Reagents and so on.
