SUPER NON-WETTING, ANTI-FINGERPRINT COATINGS FOR GLASS

摘要

Glass articles with surfaces that are both super-hydrophobic and super-oleophobic, and methods for making such articles are described. The article surfaces having contact angles of sessile drops of water and oil greater than 150° and low wetting angle hysteresis leading to low sliding angle of liquid water or oil drops. In some embodiments the water and oil contact angles are greater than 170°. Said glass article comprises a glass substrate having a surface with micro- roughness of >300 nm (rms) silica nanostructure particles deposited on the roughened surface and a selected perfluoroalkyl-Si coating on the micro-rough surface and nanostructure particles deposited thereon.
