Abstract

This invention relates to an epoxy resin monomer based on furan containing imine bonds, its preparation method, and its applications, belonging to the field of epoxy resin technology. The furan-based epoxy resin monomer introduces a five-membered ring containing oxygen into its molecular chain. The oxygen atom provides an activation site for hydrogen bonding, strengthening the non-covalent bonds between molecular chains. When subjected to external impact, the non-covalent bonds break first, absorbing part of the impact energy, thus improving the material's toughness. The introduction of dynamic imine bonds into the monomer endows the epoxy resin with recyclability. The resin product obtained after curing this epoxy resin monomer is reprocessable and biodegradable.
