Abstract:
1. A product comprising: a shape memory polymer which functions as a reversible dry adhesive comprising a shape memory polymer composition which exhibits adhesive properties when heated above its glass transition temperature wherein the shape memory polymer composition comprises a mixture of Bisphenol A/Epichlorohydrin epoxy resin with Polyoxypropylenediamine and octadecyl amine, at a mole ratio of 20:0.5:19; wherein the shape memory polymer which functions as a reversible dry adhesive may be formed around a first part and a second part under a preload force to form a temporary mechanical clamp; and the shape memory polymer which functions as a reversible dry adhesive further comprising a curved structure sufficient to facilitate a peel-off release of adhesion from the first part and the second part when the reversible shape memory polymer which functions as a dry adhesive is heated to or above its glass transition temperature.
