Engineering cohesion and adhesion through dynamic bonds for advanced adhesive materials

Abstract Adhesive materials have been widely used in almost every industrial domain. The art of the design principles of high‐performance adhesives lies in the regulation of adhesion and cohesion strengths. Compared with permanent covalent bonds, dynamic bonds, including dynamic covalent and noncovalent bonds, are vulnerable under mechanical stimuli but rebuildable, making them promising candidates to manipulate the internal and interfacial energy. In this review, we mainly discuss how dynamic bonds can be applied to adhesive materials to regulate adhesion and cohesion, simultaneously. Representative samples are rationally selected to elaborate on the engineering designs for improving the adhesive performance via incorporating dynamic bonds. We also offer a perspective on future research directions on the engineered construction of advanced adhesive materials.
