High biomass content in epoxy vitrimers: a study on bio-based and reprocessable thermosets
This study reports the development of a novel biomass-based epoxy vitrimer using bio-derived monomers and a fully bio-based cross-linking agent. Specifically, di-epoxy, tri-epoxy, and soybean oil (SO)-epoxy monomers were synthesized from renewable sources of 2,5-furandicarboxylic acid (FDCA), protocatechuic acid (PCA), and soybean oil, respectively. A fully bio-based tetra-functional thiol cross-linker was also synthesized from α-lipoic acid. The resulting epoxy resins exhibited high biomass contents (77.10% for di-epoxy, 74.30% for tri-epoxy, and 74.00% for SO-epoxy) demonstrating their sustainability. These resins, which can be cured at relatively low temperatures, exhibited exceptional mechanical properties with tensile strengths of up to 55.76 MPa. Moreover, the resins exhibited stress–relaxation behavior and reprocessing capabilities through the integration of thiol–epoxy reactions and transesterification, marking a significant advancement in the development of sustainable alternatives to conventional petroleum-based thermosets. This study underscores the potential application of these bio-based, reprocessable epoxy vitrimers to the reduction of environmental pollution and greenhouse gas emissions.
