| 摘 要： | 以聚偏氟乙烯(PVDF)为基材,分别采用直接引发原子转移自由基聚合(ATRP)和碱处理后自由基聚合的方法接枝N-异丙基丙烯酰胺(NIPAAm),合成出不同接枝率的PVDF-g-PNIPAAm共聚物,然后用相转化法制备出PVDF-g-PNIPAAm共聚温敏膜.用核磁共振(1H NMR)和X射线光电子能谱(XPS)分别对共...

| Abstract: | The poly(vinylidene fluoride)-g-poly(N-isopropylacrylamide)(PVDF-g-PNIPAAm) copolymers with different graft ratio were synthesized via grafting NIPAAm onto PVDF substrate using atom transfer radical polymerization(ATRP) and radical polymerization of alkali treated PVDF,respectively.The graft copolymers were cast by phase inversion into PVDF-g-PNIPAAm temperature sensitive membranes.The chemical structures of the graft copolymers and membranes were characterized,respectively,by 1H NMR and X-ray photoelectron... |
