Oleophobic glass substrates

摘要

A glass substrate having an oleophobic surface. The surface is substantially free of features that form a reentrant geometry and includes a plurality of gas-trapping features extending from the surface to a depth below the surface and a coating comprising at least one of a fluoropolymer and a fluorosilane. The gas-trapping features are substantially isolated from each other, and trap gas below droplets to prevent wetting of the surface.

1. A glass substrate comprising an oleophobic surface,
wherein the oleophobic surface is substantially free of features that form a reentrant geometry and comprises a plurality of gas-trapping features, wherein the plurality of gas-trapping features are open to the oleophobic surface and extend to a depth below the oleophobic surface, and are isolated from each other, and wherein the oleophobic surface comprises an open fraction of at least 0.4.
