Abstract

A surfaced-modified substrate having at least a first operating state and a second operating state, which comprises a switchable compound having at least one measurable, selectively configurable property responsive to a change in at least one preselected condition, and a selected substrate having a substrate surface adapted to have said switchable compound deposited on at least a portion of said substrate surface to form said surface-modified substrate and to enable said surface-modified substrate to selectively switch between said at least first and second operating states in response to the change in said preselected condition. The switchable compound selected should substantially retain its measurable configurable property after being deposited or grafted onto the substrate surface. A method of synthesizing the surface-modified substrate is also provided.
