Research on the Performance Improvement of Bio-based Magnolol Epoxy Resin

Against the backdrop of reducing reliance on petroleum resources in epoxy resin production and achieving enhanced performance, the development of thermosetting epoxy resins that combine sustainability with excellent overall properties has emerged as a key research direction.In this study, a magnolol-based epoxy monomer (DGEM) was synthesized using biomass-derived magnolol as the primary raw material and cured with 4,4′diaminodiphenylmethane (DDM). DGEM was then blended with bisphenol A epoxy resin
