Abstract: 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.
Key words: epoxy resin; block copolymer; self-assembly; reaction-induced microphase separation
