摘要

Stable, tough, and functional adhesion systems are urgently needed for a sustainable society. As a resolution, supramolecular scientists have introduced reversible and movable crosslinked materials into adhesion systems. Reversible crosslinks can repeatedly associate and dissociate. Therefore, reversible crosslinked materials show self-healing and stimuli-responsive properties. Moreover, movable crosslinks are topological crosslinks in which the polymer chains penetrate the cavities of cyclic molecules. The sliding of the movable crosslinks with deformation enabled the achievement of materials showing high toughness and self-relaxation. Adhesion systems with reversible and movable crosslinks have improved adhesion and cohesion, stability, and functionality. This novel concept for the design of adhesion systems is expected to increase the lifetime of adhesives and ameliorate environmental problems.
