通过嵌段共聚物在环氧树脂中的微相分离能够构建具有不同形貌纳米结构的热固性树脂,从而改善环氧树脂的性能。自组装机理和反应诱致微相分离机理作为环氧树脂中构建纳米结构的机理已得到众多环氧树脂研究工作者的认可,这为进一步于环氧树脂中构建新型的纳米结构提供了有利的支撑。本文针对自组装机理和反应诱致微相分离机理进行了阐述,并对通过两种机理在环氧树脂中构建纳米结构的研究进展及纳米微相结构对热固性树脂性能的影响做了概述,以期对环氧树脂更为广泛的应用提供一定的帮助。

Nanostructured thermosetting resins with different morphologies can be constructed by microphase separation of block copolymers in epoxy resins,thereby improving the properties of epoxy resins.Self-assembly mechanism and reaction-induced microphase separation mechanism have been recognized by many epoxy resin researchers as the mechanism for constructing nanostructures in epoxy resins,which provides favorable support for further construction of new nanostructures in epoxy resins.In this paper,the mechanism of self-assembly and the mechanism of reaction-induced microphase separation are expounded,and the research progress of constructing nanostructures in epoxy resin by two mechanisms is described.In this paper,the effect of nano-microphase structure on the properties of thermosetting resins is summarized,in order to provide some help for the wider application of epoxy resins.
