【摘要】：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.
[Abstract]:Polymerization-induced self-assembly is a novel self-assembly strategy based on active polymerization, which can be used to prepare aggregates with different morphologies in a higher solid content system in one step. The reversible addition-break chain transfer polymerization (Raft) is used for active polymerization. A novel P4VP-b-PBz MA block copolymer was synthesized in ethanol solution. 鈫扺orm. 鈫扵he structure and size of aggregates can be effectively controlled by the change of P4VP in solvent-friendly segments. In addition, the process of structural transformation of P4VP-b-(PHPMA-co-PBz MA-triblock copolymers during self-assembly induced by polymerization was studied by random copolymerization.
