摘要 采用原子转移自由基聚合(ATRP)方法合成了两亲性嵌段共聚物PSt-b-PAA。用1H NMR和GPC等手段对活性聚合进行了确认,对嵌段共聚物的结构进行了表征。两亲性嵌段共聚物在离子液体1-丁基-3-甲基咪唑六氟磷酸盐([BM IM][PF6])中形成胶束溶液。用透射电子显微镜(TEM)观察聚合物在离子液体中形成胶束的纳米结构。当疏水链长固定时,胶束的自组装形状主要依赖于亲水链的长度。两亲性共聚物在离子液体中可自组装成可控制结构的纳米胶束,这种纳米胶束可应用在很多领域。 Amphiphilic block copolymer PSt-b-PAA was synthesized by means of the atom transfer polymerization（ATRP）.Polymerization was confirmed by means of 1H NMR and GPC,and the structure of the block copolymers were characterized.Amphiphilic block copolymers was in ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate（） form the micellar solution.The formation of polymer micelles in ionic liquid was observed with transmission electron microscopy（TEM）.When the hydrophobic chain length was fixed,the shape of micelle self-assembly mainly depended on the length of hydrophilic chain.Amphiphilic copolymers in ionic liquids can self-assemble into micelles can be controlled structure,and such micelles can be applied in many fields.
