Abstract
A process for creating hydrophobic and oleophobic glass surfaces. The process consists of heating a glass article to temperatures near the glass softening point and pressing a textured mold into the glass article to create surface texture. The mold texture is selected to have dimensions that convey hydrophobicity and oleophobicity to the glass article when combined with appropriate surface chemistry. The surface features are controlled through choice of mold texture and through process parameters including applied pressure, temperature, and pressing time. Articles made by this process are also described.
