摘要：

分离膜是一种用于浓缩、分离、提纯的功能材料。但分离膜由于自身材料的限制，存在易受污染、使用寿命短等问题。在分离膜上接枝PNIPAAm，可以改善分离膜的亲水性，获得抗污染性；同时可获得温敏性，得到温控开/关分离膜。本文论述了近年来接枝PNIPAAm温敏改性在温控开/关分离膜上的研究概况及进展

Separation membranes, as functional materials, are applied to concentration, separation, refinement, etc. However, due to the limitation from the properties of component materials, separation membranes are vulnerable to be polluted and short-life. Recently, researches have fund that grafting poly(N-isopropylacrylamide) (PNIPAAm) on separation membranes directly, can confer hydrophily and pollution resistance on them. At the same time, owning to the thermosensitivity of PNIPAAm, the grafted separation membranes become thermally on-off switching separation membranes. This paper presents recent researches on them.
