Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composite dry adhesive comprising: an adhesive layer comprising a shape memory polymer; and a resistive heating layer comprising a shape memory polymer composite on the adhesive layer, the shape memory polymer composite including conductive particles dispersed in a shape memory polymer matrix, wherein the conductive particles have a concentration sufficient to form a conductive path through the resistive heating layer, wherein the resistive heating layer includes one or more isolated contact regions at least partially surrounded by a continuous resistive region, the one or more isolated contact regions including the conductive particles at a first concentration and the continuous resistive region including the conductive particles at a second concentration, the first concentration being higher than the second concentration. 2. The composite dry adhesive of claim 1 , wherein the first concentration is from about 25 wt. % to about 30 wt. %, and wherein the second concentration is from about 10 wt. % to about 20 wt. %. 3. The composite dry adhesive of claim 1 , wherein the one or more isolated contact regions are surrounded by the continuous resistive region in a plane of the resistive heating layer. 4. The composite dry adhesive of claim 1 , wherein the resistive heating layer includes from 5 to 500 of the isolated contact regions.
