About Paper:

Biobased adhesives are a relatively new development that have the potential to replace conventional petroleum-based adhesives, reducing the use of fossil fuels. However, biobased glues have yet to be comparable with petroleum adhesives across the board in cost, strength, and industrial scaling, limiting their marketability. Inspired by the chemistry that mussels use to adhere to rocks, a biobased epoxy created in the Wilker lab shows promise as a scalable, 100% biobased adhesive. This research intends to discover what kinds of additive fillers can improve this biobased epoxy adhesive's strength and cost. In particular, trends in material type, particle size, and filler amount will be analyzed. Various fillers are added to the biobased adhesive for each combination of filler and particle size. The modified adhesives are then applied to wood substrates, cured, and tested for lap-shear strength. Preliminary results show that most filler additions greatly increase the strength of the adhesive, with smaller particle sizes being more effective at increasing adhesion strength. The findings from this research will help inspire stronger, more effective biobased adhesives, giving them a better edge in the adhesives market. Keywords: [no keywords provided]
