Abstract
A method of forming a lignin-based biomass epoxy resin is provided, which includes: (a) mixing a lignin, an acid anhydride compound, and a solvent to react for forming a first intermediate product, (b) reacting the first intermediate compound with a first polyol to form a second intermediate compound, and (c) reacting the second intermediate compound with an epoxy compound to form a lignin-based biomass epoxy resin.
