主　　题：Epoxy resin Magnolol Self-curing Fully bio-based Antimicrobial properties 

摘      要：Bio-based epoxy thermoset prepared from renewable biomass raw materials can alleviate fossil energy crisis and reduce environmental pollution,which satisfies the needs of sustainable social *** this study,a bio-based epoxy thermoset precursor(MGOL-EP) was synthesized from a naturally occurring magnolol through a facile and efficient one-step *** the fully bio-based epoxy thermoset(MGOL-EP-SC) was obtained by self-curing without adding any other ***-EP-SC revealed an extremely high glass-transition temperature(T_(g)) of 265℃ and char yield of 53.2%(in N;),which were at the highest level among the fully bio-based epoxy thermosets reported so *** addition,when the MGOL-EP was cured with 4,4’-methylenedianiline(DDM),T_(g)of the MGOL-EP/DDM was decreased by 61℃ and the other comprehensive performance had also been decreased,which was due to a reduction in biphenyl structure content and cross-linking density by adding the external curing ***,the MGOL-EP-SC presented certain killing rate(48.4%) to Staphylococcus *** findings provide a new design strategy for engineering high-performance and functional epoxy thermoset with high biomass content.
