A reversible adhesive system for coupling together two objects may consist of two shape memory polymers with molecular “hooks and loops” on the surfaces (i.e. the surface away from each of the objects). Utilizing the shape memory properties of the polymers, the molecular hooks and molecular loops may be brought together to form non-covalent bonds, leading to macroscopic adhesion. Upon heating, the adhesive bond can be separated with a small peeling force. The adhesive bonding and debonding can be repeated for multiple cycles with significant adhesion retention. |
