Abstract
A composite dry adhesive includes (a) an adhesive layer comprising a shape memory polymer and (b) a resistive heating layer comprising a shape memory polymer composite on the adhesive layer. The shape memory polymer composite includes conductive particles dispersed in a shape memory polymer matrix, where the conductive particles have a concentration sufficient to form a conductive path through the resistive heating layer.
