| 摘 要： | 通过可逆加成-断裂链转移(RAFT)的聚合方法,合成了分别含有苯硼酸基元和葡萄糖基元的聚(N-异丙基丙烯酰胺)-b-聚(丙烯酰胺基苯硼酸)(PNIPAM-b-PAPBA)和聚(N-异丙基丙烯酰胺)-b-聚(丙烯酰葡萄糖胺)(PNIPAM-b-PAGA)二嵌段聚合物.由于苯硼酸和葡萄糖基元之间在弱碱性条件下(pH9.3)形成硼酸酯共价键,两种二嵌段聚合物的水溶液混合后能自发形成以PAPBA/PAGA络合物为核,PNIPAM为壳层的高分子复合物胶束.由于硼酸酯共价键在pH值和葡萄糖浓度改变时能可逆形成和断裂,以及胶束PNIPAM壳层的温敏性,所制备的基于苯硼酸/葡萄糖可逆共价键的高分子复合物胶束对pH、葡萄糖和温度具有多重响应性.
