Lignin-based epoxy resins with improved mechanical properties
Epoxy resins are widely used in various high-performing (e.g., structural) and commodity products. They are frequently found in electronics, metal coatings, composites, plastics, and adhesives. Currently, the epoxy resin market is dominated by materials containing bisphenol A and other chemicals harmful to the environment. Lignin can be employed to overcome this issue without sacrificing any mechanical and thermal properties, but since it is not reactive in its native form, a functionalization step is required first.
Our technology involves the preparation of novel epoxy resins using lignin in specific formulations. The epoxy resins proposed are composed of three components: a lignin, a functionalizing agent, and an epoxide. While lignin has been combined with an anhydride or epoxide before, literature on using a combination of all three components is extremely limited.
Such novel epoxy resins can greatly support sustainable development and the establishment of a circular economy in various industries, such as automotive, construction, and electronics.
