Abstract
Official abstract text for this publication.
A process for manufacturing a hydrophobic glazing by: (i) forming a carbon-rich SiO x C y layer at a surface of a mineral glass substrate via CVD by contacting the surface with a stream containing C 2 H 4 , SiH 4 , and CO 2 with an C 2 H 4 /SiH 4 ratio of less than or equal to 3.3 by volume, at a temperature of between 600° C. and 680° C.; (ii) forming a SiO 2 layer or a carbon-poor silicon oxycarbide layer with a mean C/Si ratio of less than 0.2 on the carbon-rich SiO x C y layer, thereby obtaining a layered substrate; (iii) annealing and/or shaping the layered substrate at a temperature of between 580° C. and 700° C.; (iv) activating the SiO 2 layer or the carbon-poor silicon oxycarbide layer by plasma treatment or acidic or basic chemical treatment; and (v) grafting, by covalent bonding, a fluorinated hydrophobic agent to the surface of the SiO 2 layer or the carbon-poor silicon oxycarbide layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for manufacturing a hydrophobic glazing, the process comprising: forming a carbon-rich silicon oxycarbide (SiO x C y ) layer at a surface of a mineral glass substrate by chemical vapor deposition (CVD) over at least a portion of the surface of the substrate by contacting the surface with a stream of reactive gases comprising ethylene (C 2 H 4 ), silane (SiH 4 ), and carbon dioxide (CO 2 ) with an ethylene/silane (C 2 H 4 /SiH 4 ) ratio by vol…
