【摘要】 通过原子转移自由基(ATRP)的方法,将聚N,N-二甲基甲基丙烯酸乙酯(PDMAEMA)作为末端嵌段链接到F127(PEO-b-PPO-b-PEO)共聚物两端,合成了一种新的多嵌段两亲性聚合物(PDMAEMA_n-b-F127-b-PDMAEMA_n)。以此嵌段聚合物为添加剂对聚醚砜(PES)膜进行共混改性,并以F127为参照样,详细的研究了合成的两亲性多嵌段共聚物对共混膜的亲水改性效率,在膜中的稳定性,以及共混膜在对温度和PH刺激的响应行为。更多还原

【Abstract】 F127-based(F127,PEO-b-PPO-b-PEO) amphiphilic multi-block copolymers containing poly(N,N-dimethylamino -2-ethyl methacrylate)(PDMAEMA) end blocks(PDMAEMA_n-b-F127-b-PDMAEMA_n) were synthesized by ATRP method,and then used as additives in the polyethersulfone(PES) porous membranes preparation by phase inversion method.Compared to the F127,the synthesized copolymers were more effective in improving the membranes hydrophilicity,and better hydrophilicity was obtained for additives with longer PDMAEMA block.The water permeation results indicated that the additives had endowed membranes with temperature and pH responsive behavior.更多还原
