Abstract
A surface with selectable adhesion is achieved by a shape memory alloy that is at least partly coated with a polymer forming a surface structure, thus allowing the adhesion force of the surface to be controlled.
Claims16
An article having at least one surface having switchable dry adhesion, wherein this surface comprises at least one shape memory alloy coated at least partly with at least one polymer,
- wherein the at least one shape memory alloy is capable of forming a surface structure changing the surface area available for dry adhesion,
- wherein the surface structure is a microtexture comprising a lateral dimension of 100 μm to below 500 μm and a height more than 0.5 μm.
An article, comprising:
- an article having at least one surface having switchable dry adhesion, said at least one surface comprising at least one shape memory alloy coated at least partly with at least one polymer,
- wherein the at least one shape memory alloy forms a surface structure, thereby changing a surface area available for dry adhesion,
- wherein the article contains no adhesive,
- wherein the surface structure is a microtexture comprising a lateral dimension of 100 μm to below 500 μm and a height more than 0.5 μm.
