Epoxy Resin Thermosets Derived from Vanillin (RFT-487)
Thermosetting polymers and composites are widely used in industry due to their low density, good mechanical properties, low cost, and dimensional stability. However, most resins are synthesized primarily using petroleum-based chemicals. Researchers at NDSU have developed vanillin-based epoxy resins synthesized from the reaction between vanillin and diamines to form a Schiff base (I), which is then glycidated to form an epoxy resin (II). The resin may then be crosslinked using amines to form a thermoset coating (the example showing reaction with a diamine that leads to a crosslinked coating). Vanillin from any source may be used, including from lignin, which could expand the opportunity for value-added uses of lignin.
- Low-cost bio-based resin
- Do not contain bisphenol-A
- Provides another use for a waste product
- Applications in coatings, composites, and adhesives
The technology includes a vanillin-derived Schiff base, which may be glycidated to create a bio-based epoxy resin. An amine is then used to crosslink the resin to produce a cured coating or similar product.
This technology is patent pending with fully preserved PCT patent rights and is available for licensing/partnering opportunities.
