摘要
聚N-异丙基丙烯酰胺(PNIPAAM)是现今研究最多、发展最快的一种新型热敏性聚合物,但其较差的机械强度限制了它的应用效果。为克服这一不足,将PNIPAAM接枝于其它力学性能较好的高分子基材上是一种可行的方法,同时也可在一定程度上赋予高分子基材某些特殊的性能。综述了近年来有关聚N-异丙基丙烯酰胺的主要接枝聚合方法,如射线辐射接枝、溶液自由基接枝、光引发接枝、低温等离子体接枝等以及其国内外的研究现状。
Poly (N-isopropylacrylamide) (PNIPAAM) is a new type of thermo-sensitive polymer which is an area of extensive study and gaining rapid development nowadays. However, the low intensity of PNIPAAM restricts its application fields seriously. To remedy this deficiency, grafting PNIPAAM to other macromolecule materials with better physical property becomes a feasible method. Meanwhile, the macromolecule materials will be endowed with some special properties after grafting. This reviews the present researches working on the grafting methods of N-isopropylacrylamide including radiation grafting, solution free radical grafting, photo- induced grafting, and low temperature plasma grafting.
