聚合诱导自组装是一种基于活性聚合的新型自组装策略,其特点是可以在较高固含量体系中一步制备不同形貌的聚集体结构.利用可逆加成-断裂链转移聚合(RAFT)活性聚合,在乙醇溶液中合成新型P4VP-b-PBz MA嵌段共聚物,发现聚合诱导自组装过程中聚集体结构发生球→蠕虫→囊泡的连续转变.亲溶剂链段P4VP的变化可有效调控聚集体的结构和尺寸.此外,采用无规共聚方法,研究了P4VP-b-(PHPMA-co-PBz MA)三嵌段共聚物在聚合诱导自组装过程中组装体结构的转变过程.
Polymerization-induced self-assembly is a new type of self-assembly strategy based on living polymerization, which is characterized by one-step preparation of aggregates of different morphologies in higher solid content systems.Reversible addition-fragmentation chain transfer polymerization (RAFT) Polymerization, a novel P4VP-b-PBz MA block copolymer was synthesized in ethanol solution, and it was found that the polymerization of the P4VP-b-PBz block copolymer resulted in the continuous transformation of aggregates from sphere → worm to vesicle. Aggregate structure and size.In addition, random copolymerization method was used to study the transition of the assembly structure of P4VP-b- (PHPMA-co-PBz MA) triblock copolymer during the polymerization-induced self-assembly.
