新型技术引发/辅助聚合诱导自组装研究进展

Research Progress in Initiation/Assisted Polymerization-Induced Self-Assembly by Novel Technologies

聚合诱导自组装(PISA)作为一种高效制备具有可控形貌组装体的技术,可以在形成嵌段共聚物的同时原位自组装形成组装体,该技术具有操作简单、产物固含量高的优势。大部分PISA采用热引发的方式,该方法通常需要大量时间和较高的温度。在过去的几年里,更加环保节能的新型引发机制和辅助手段应运而生。总结了采用光、酶、超声、微波和氧化还原等新型技术引发/辅助聚合诱导自组装的研究进展。

Polymerization-induced self-assembly(PISA),as an efficient technology for the preparation of assemblies with controllable morphology,can form assemblies in situ while forming block copolymers,which has the advantages of simple operation and high solid content.Most PISAs are heat-primed,which typically requires a lot of time and high temperatures.In the past few years,new initiation mechanisms and auxiliary means that are more environmentally friendly and energy-saving have emerged.In this paper,the research progress of initiating/assisting polymerization-induced self-assembly using new technologies such as light,enzyme,ultrasound,microwave and redox was summarized.
