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-PBzMA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-PBzMA)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 (PISA) is a robust and highly feasible route to prepare well-defined nanoparticles in a relevant high concentration reaction system. The morphology transition of novel di-block copolymer P4VP-b-PBzMA during PISA was investigated based on reversible addition-fragmentation chain transfer (RAFT) polymerization. Spherical, worm-like and vesicular aggregates were observed at different reaction periods. The chain length of P4VP block could adjust the morphologies and dimension of aggregates. In addition, hydroxypropyl methacrylate was introduced into polymerization system to figure out its impact on morphology transition during the PISA process.

Key words: polymerization-induce self-assembly, RAFT polymerization, P4VP-b-PBzMA di-block copolymer
