Abstract

There has been an ongoing interest in using proteins as more environmentally friendly substitutes for the existing synthetic adhesives. Poor water resistance is a particular shortcoming of protein-based adhesives, which negatively affects their outdoor functionality. In this study, we systematically investigated if water solubility of the protein, addition of a phenolic compound such as tannic acid, and protein-polyphenol complexation could improve the water resistance of protein-based adhesives. It was found that the synergetic effects of these parameters can yield commercial-level water resistance.
