Multilayer thermo-reversible dry adhesives

A method comprising:

• forming a multilayer thermo-reversible dry adhesive comprising:
• forming a first layer by curing a first component, a second component, and a third component;
• forming a second layer over the first layer comprising pouring a mixture of a fourth component and a fifth component over the first layer and curing the second layer;
• and
• post-curing the first and second layers to form a multilayer thermo-reversible adhesive having a curved structure at a first temperature and having a relatively flat structure at a second temperature with a load applied.

A method comprising:

• providing a multilayer thermo-reversible dry adhesive comprising at least one dry adhesive layer and at least one shape memory polymer layer;
• heating the multilayer thermo-reversible dry adhesive to a temperature higher than the glass transition temperature of the shape memory polymer;
• imposing a load on the multilayer thermo-reversible dry adhesive while cooling to a temperature below the glass transition temperature of the shape memory polymer, so that the multilayer thermo-reversible dry adhesive forms a strong adhesive bond to an underlying substrate;
• and
• releasing the multilayer thermo-reversible dry adhesive from the substrate by heating the multilayer thermo-reversible dry adhesive to a temperature above the glass transition temperature of the shape memory polymer.
