本工作发展了一种简便、实用的制备抗菌聚醚砜（PES）膜的方法。以聚醚砜嵌段-聚甲基丙烯酸二甲氨基乙酯（PDMAEMA-b-PES-b-PDMAEMA）为共混添加剂，采用传统的非溶剂诱导相分离（NIPS）工艺制备了PES共混膜。共聚物添加剂中的亲水性PDMAEMA链在成膜过程中自发地向膜和凝固浴（通常为水）之间的界面迁移。然后通过分别与1，3-丙磺酸内酯（1，3-PS）和1-溴癸烷反应，将在所制备的共混膜上富集的PDMAEMA链季铵化。从1，3-PS处理获得的两性离子PES膜显示出显着改善的可渗透性和血液相容性。用溴代癸烷处理的阳离子PES膜对大肠杆菌有较好的抗菌活性。
A facile and practical method for fabricating antifouling and antimicrobial poly(ether sulfone) (PES) membranes is developed in this work. A PES blend membrane was first fabricated by a traditional nonsolvent induced phase separation (NIPS) process with a reactive amphiphilic copolymer poly(ether sulfone)-block-poly(2-(dimethylamino) ethyl methacrylate) (PDMAEMA-b-PES-b-PDMAEMA) as the blending additive. The hydrophilic PDMAEMA chains in the copolymer additive spontaneously migrated toward the interfaces between membrane and coagulant bath (usually water) during membrane formation. The enriched PDMAEMA chains on the as-made blend membranes were then quaternized by reacting with 1,3-propane sultone (1,3-PS) and 1-bromodecane, respectively. The zwitterionic PES membranes obtained from 1,3-PS treatment showed significantly improved antifouling ability and hemocompatibility. In another case, the resulting cationic PES membranes treated with 1-bromodecane exhibited excellent antibacterial activities against Es...
