Designing and preparing bio‐based epoxy monomers to substitute hazardous and nonrenewable bisphenol A (BPA)‐type epoxide are important for the development of new epoxy resins under the concept of healthy and sustainable concept. In this work, a “green” bifunctionality epoxy monomer derived from eugenol (EGE‐EP) was fabricated by epoxidation functionalization of unsaturated double bond as well as using epichlorohydrin to epoxidize phenolic hydroxyl group. The effects of different hardeners on the properties of EGE‐EP were analyzed, and the E51 epoxy cured with the same hardeners was employed as a reference. The results indicate that the EGE‐EP/hardeners present desired curing behavior, mechanical performances, and thermal stability which are comparable to the commercial E51/hardeners epoxy resin. Most importantly, all EP/hardeners samples exhibit a lower onset temperature compared to E51/hardeners systems reflecting a faster curing properties of the EGE‐EP/hardeners mixtures. Meanwhile, an obvious improvement of char yield is found in EGE‐EP/hardeners in contrast to E51/hardeners thus possessing potential for flame retardancy applications. This study proposes an innovative path to prepare bio‐based epoxy monomers as an alternative to BPA‐type epoxide, which is of significance for eco‐friendly epoxy resins and high‐value utilization of biomass.
