Bio-Based Wood Adhesive from Camelina Protein (a Biodiesel Residue) and Depolymerized Lignin with Improved Water Resistance.

ABSTRACT: The aim of this study was to improve water resistance of camelina protein (CP) for wood adhesives with depolymerized lignin. Kraft lignin was depolymerized by H₂O₂-induced oxidation in the presence of ultrasound (US) irradiation to reduce lignin's particle size and thermal stability and increase the hydroxyl group. Coupling with depolymerized lignin camelina protein exhibited increased hydrophobicity. Fluorescence spectroscopy analysis revealed that the oxidation treatment of lignin further stimulated the hydrophobization effect of the protein-lignin copolymer due to the increased reactivity of depolymerized lignin to camelina protein. Accordingly, the water resistance of CP-lignin adhesives was significantly improved. When copolymerized with US-induced oxidized ligni
