Abstract
A reusable attaching apparatus includes (a) a reversible adhesive comprising a shape memory polymer and (b) a mounting structure bonded to the reversible adhesive. The shape memory polymer has a glass transition temperature (Tg) and comprises a deformable state at temperatures above the Tg and a rigid state at temperatures below the Tg.
Claims20
A method of attaching a reusable attaching apparatus to a surface, the method comprising:
- providing a reusable attaching apparatus comprising:
- a mounting structure bonded to a reversible adhesive, the reversible adhesive comprising a shape memory polymer having a glass transition temperature (Tg) and comprising a deformable state at temperatures above the Tg and a rigid state at temperatures below the Tg;
- heating the reversible adhesive to a temperature above the Tg, the shape memory polymer reaching the deformable state;
- during the heating, contacting the reversible adhesive with a mounting surface and applying pressure thereto, the reversible adhesive deforming and increasing in contact area with the mounting surface;
- and
- cooling the reversible adhesive to a temperature below the Tg, the shape memory polymer adopting the rigid state and the reversible adhesive adhering to the mounting surface with an adhesion strength of at least about 1 MPa, thereby attaching the reusable attaching apparatus to the mounting surface.
