摘要：聚合诱导自组装(PISA)是一种在高浓度溶液中可连续大量制备纳米材料的新技术,结合计算模拟方法,研究其动力学过程可强化对PISA的认识和调控.通过耗散粒子动力学(DPD)模拟,研究了ABC三嵌段共聚物的聚合诱导自组装过程.先利用亲溶剂A链段引发B单体聚合,随着疏溶剂B链段的增长,AB二嵌段共聚物可组装并发生聚集体结构的连续转变,由球形胶束→蠕虫状胶束→层状结构→囊泡.再将C单体逐步聚合到AB共聚物上,调控C链段的亲疏溶剂性,可聚合诱导组装或解组装形成不同的ABC三嵌段共聚物聚集体.
Polymerization-induced self-assembly （PISA） is a new robust strategy to produce concentrated dispersions of block copolymer nano-objects. Insight into the dynamic process can promote the development of PISA by computer simulations. In this work, dissipative particle dynamics simulations （DPD） with a reaction model were employed to investigate the PISA behavior of ABC triblock copolymer. The polymerization of solvophobic B block was firstly performed using solvophilic macromolecular initiator A to fabricate AB copolymer. The continuous morphology transition from spherical micelle to wormlike micelle, to lamellae and finally to vesicle was observed during the process. Then, the polymerization of C block was further carried out and induced the different ABC triblock copolymer aggregates by tuning the interaction between C block and solvent （solvophobic or solvophilic）.
