Abstract | As a sustainable alternative for petroleum-based adhesives, soy meal (SM) has emerged as an ideal feedstock for biobased adhesives because of its availability, abundance, and nontoxicity. However, SM-based adhesives do not exhibit a superior wet bonding performance, toughness, and mildew resistance. In this paper, a simple Fe3O4/MoS2 nanozyme is synthesized, which could not only catalyze the tyrosine to prepare DOPA, endowing the SM-based adhesive with strong interfacial adhesion, but also serve as a physical cross-link to coordinate complexes to strengthen and toughen the adhesive bonding. Inspiringly, DOPA-assisted-dispersing Fe3O4/MoS2 nanozyme destructs the mold due to its sharp edge and forms a robust carbonization char layer to block the flame. The formulated adhesive presents a high wet shear strength (1.28 MPa), prolonged antimildew shelf life of 15 days, and remarkable antiflame properties (LOI = 31.0%). The adhesive synthesized from this facile, sustainable, and efficient nanozyme catalytic strategy is low cost with high bonding strength. |
