Title:

SWITCHABLE SURFACES

Document Type and Number:

WIPO Patent Application WO2003055590

Kind Code:

A3

Abstract:

A substrate having a surface with reversibly switchable properties. The surface comprises a nanolayer of a material that switches from a first conformation stateto a second conformation state when an external stimulus is applied. When the nanolayer is in the first conformation state, the surface is characterized by a first property, and when the nanolayer is in the second conformation state, the surface is characterized by a second property.
