| description | Abstract Introducing dynamics into bio-based adhesives shows many advantages on rendering mechanics and functions. However, the efficient employment of dynamic chemistry in achieving robust, stable, and reusable bio-based adhesives derived from low-value residues remains elusive. Here, we facilely develop a reused camellia meal-based adhesive integrating excellent mechanical robustness, environment durability, and mildew resistance through the cooperation of dual dynamic bonds. By deliberately harnessing dynamic covalent bonds as the first strong interlinking and dynamic noncovalent bonds as the second weak interaction, our strategy allows the resulting adhesive with a much-improved adhesion strength (2.1/1.06 MPa to wood in dry/wet condition) and remarkable adhesion maintenance against harsh environmental factors (organic solvents, salt, acid, alkali, temperature, soaking time). By virtue of these abundant dynamic bonds, this adhesive not only escapes from the inherent drawback of biomaterials to display enlarged anti-mildew efficacy, but also is capable of reprocessing to gain reusability. Combining these desirous characters with the simple two-step fabrication process, this study provides a great potential for the development of high-performance bio-based adhesives sustainably and intelligently. |
