Method of providing photopatterned functional surfaces

An article is prepared with surface regions having different contact angles. A reactive silane material is attached to a surface having a reactive tail component that is contacted with a first corresponding reactant, followed by imagewise UV exposure to cause imagewise reaction of the reactive tail...

Beschreibung
Zusammenfassung:	An article is prepared with surface regions having different contact angles. A reactive silane material is attached to a surface having a reactive tail component that is contacted with a first corresponding reactant, followed by imagewise UV exposure to cause imagewise reaction of the reactive tail component and first corresponding reactant, forming reacted regions and latent reaction regions. After rinsing, a second corresponding reactant that is capable of reaction with the reactive moiety is applied. Uniform UV exposure leads to a second reaction product only in the latent reaction regions. After rinsing, first regions comprise exclusively the first reaction product and second regions comprising exclusively the second reaction product. These first and second regions have contact angles that differ by 10-110 degrees. A composition can be applied that is exclusively attracted to either the first regions or the second regions, but not to both the first and second regions.
