Biomass-based monomer design and closed-loop recycling strategy development for epoxy resin thermoset

<正>Epoxy resin thermosets (ERTs) are indispensable materials in daily life, particularly in composites, construction, transportation, and aviation. The highly cross-linked frameworks in cured ERTs provide excellent durability and stability. However, their chemical inertness,which is a double-edged sword, poses significant recycling challenges,thereby threatening the environment [1]. In addition, the raw material for ERTs, fossil-based bisphenol A (BPA), has potential adverse health effects on humans. The critical challenge is to develop suitable ERT candidates that are both renewable at the source and recyclable at the end. It requires ingenious structure and molecular design to simultaneously entrust polymer materials with excellent performances.
