Abstract

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.
