| 摘要 |
An article is described, comprising: a) a substrate having first regions having a microstructured surface and second regions not having a microstructured surface, where the first regions and second regions are relatively differentially wettable; and b) a patterned layer formed on the substrate from a coating that preferentially wets the relatively more wettable regions of the substrate. A method of making a patterned coating is also described, comprising the steps of: a) providing a substrate having first regions having a microstructured surface and second regions not having a microstructured surface, where the first regions and second regions are relatively differentially wettable; and b) coating the substrate with a coating material that preferentially wets the relatively more wettable regions of the substrate to form a patterned layer on the substrate.
