  Disclosed is a novel room-temperature curable bio-based epoxy vitrimer with a simple design of the chemical structure. A hempseed oil-derived glycidyl ester type epoxy (HOEP) was synthesized and then blended with a bisphenol A epoxy (DER331) to manipulate the properties of the resulting vitrimer s. An aliphatic amine hardener, diethylenetriamine (DETA), was selected as hardener to realize the room temperature curing in presence of triethanolamine (TEOA) as the catalyst. Unlike the traditional glycidyl ether epoxy-amine the thermosets which are based on stable C-N and ether linkages, the epoxy vitrimer herein includes ester bonds with HOEP and hydroxyls formed from the reaction of amine and epoxy in its cross-linked network. Dynamic transesterification (DTER) between the ester bonds and hydroxyls take place at elevated temperatures, imparting the vitrimer significant stress relaxation behavior and repairability. This provided a viable method to produce room temperature curable epoxy vitrimer s.
