Patent ID: 8685528

Claim:
A product comprising: a thermo-reversible dry adhesive comprising: a dry adhesive layer and; an adhesive backing layer comprising a shape memory polymer having a glass transition temperature connected or attached to the dry adhesive layer, said backing layer including a first surface adjacent the dry adhesive layer capable of conforming to the surface topography of a first substrate to which the adhesive layer is applied and thereby forming a first shape conforming to said surface topography at a first temperature that is below the glass transition temperature; wherein the thermo-reversible dry adhesive is constructed and arranged to change to a second shape at a second temperature that is above the glass transition temperature without the application of a load, the second shape being conducive to removing the thermo-reversible dry adhesive from the first substrate at temperatures that are above and below the glass transition temperature; and wherein the dry adhesive comprises a soft dry adhesive having a glass transition temperature between âˆ’90Â° C. and 200Â° C. and said shape memory polymer has a glass transition temperature between 25Â° C. and 90Â° C.
