Abstract
Described herein are glass substrates having oleophobic surfaces that are substantially free of features that form a reentrant geometry. The surfaces can include a plurality of gas-trapping features, extending from the surface to a depth below the surface, that are substantially isolated from each other. The gas-trapping features are capable of trapping gas below any droplets that are contacted with the surface so as to prevent wetting of the surface by the droplets.
