| description | 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.
L'invention concerne des articles en verre qui sont super-hydrophobes et superoléophobes, et des procédés de fabrication de tels articles. Les surfaces des articles ont des angles de contact de gouttes sessiles d'eau et d'huile supérieurs à 150° et une hystérésis de l'angle de mouillage faible qui conduit à un faible angle de glissement de gouttes d'eau ou d'huile liquides. Selon certains modes de réalisation, les angles de contact de l'eau et de l'huile sont supérieurs à 170°. Ledit article en verre comprend un substrat en verre présentant une surface à micro-rugosité > 300 nm (rms), des particules de nanostructure de silice déposées sur la surface rugueuse,et un revêtement de perfluoroalkyl-Si sélectionné sur la surface micro-rugueuse et les particules de nanostructure déposées sur ladite surface. |
