水相光引发聚合诱导自组装制备嵌段共聚物纳米材料
Preparation of Diblock Copolymer Nano-objects by Aqueous Photoinitiated Polymerization-induced Self-assembly
摘要
Abstract
Poly(glycerol monomethacrylate) (PGMA) and sodium phenyl-2,4,6-tri-methylbenzoylphosphinate (SPTP) were used as macro-RAFT agent and initiator,respectively.A series of poly (glycerol monomethacrylate)-b-poly (2-hydroxypropyl methacrylate) (PGMA-b-PHPMA) diblock copolymer nano-objects were prepared by aqueous visible light-mediated RAFT dispersion polymerization of HPMA.The kinetic of PISA was investigated,and a remarkably diverse set of complex morphologies (spheres,worms,and vesicles) have been prepared by aqueous photo-PISA under mild conditions (water medium,visible light,and room temperature),then the effect of reaction conditions on the morphology of nano-objects was investigated.The polymerization can be activated or deactivated by a simple "ON/OFF" switch of the light source.关键词
