WebAug 18, 2024 · Biobased epoxy thermoset polymers were prepared from lignin hydrogenolysis oils produced from native hardwood lignin. Native lignin in Eucalyptus nitens and Eucalyptus saligna wood was reacted in situ under Pd-catalyzed mild hydrogenolysis conditions to give depolymerized lignin oils in yields up to 98 wt %. Reacting these lignin … WebOct 1, 2024 · In summary, we prepared biobased epoxy vitrimers based on disulfide linkages by a catalyst free method of curing ESO with APD as a curing agent. By adjusting curing time, the crosslink density and thus the physical properties of ESOV can be tailored. The glass transition temperature, tensile strength and Young’s modulus increased … chinees restaurant in almere stad
