Case number: #22482
A dry shape memory adhesive material for adhering a target surface in the presence of fluid and for providing tunable mechanical contraction of an adhered surface. The dry shape memory adhesive material is pre-stretched and dried to provide an adhesive structure that implements a hydration-based shape memory mechanism to achieve both uniaxial and biaxial contractions of the adhered surface. According to preferred embodiments, the shape memory adhesive material includes a combination of one or more hydrophilic polymers or copolymers, one or more amine coupling group, and one or more cross linkers.
