CA 2434560

Methods and articles are disclosed in which a substrate is provided with a photo-induced hydrophilic surface by forming a photo-induced hydrophilic coating on the substrate by spray pyrolysis, chemical vapor deposition, or magnetron sputter vacuum deposition. The coating can have a thickness of 50 .ANG. to 500 .ANG., a root mean square roughness of less than 5, preferably less than 2, and photocatalytic activity of less than 3.0 x 10-3 cm-1 min-1 .plusmn. 2.0 x 10-3 cm-1 min-1. The substrate includes glass substrates, including glass sheets and continuous float glass ribbons.

La présente invention concerne des procédés et des articles dans lesquels un substrat est pourvu d'une surface hydrophile photo-induite réalisée par un revêtement hydrophile photo-induit formé sur le substrat par pyrolyse par pulvérisation, dépôt chimique en phase vapeur ou dépôt sous vide par pulvérisation magnétron. Le revêtement peut avoir une épaisseur comprise entre 50 .ANG. et 500 .ANG., une rugosité en moyenne quadratique inférieure à 5 et de préférence inférieure à 2 et une activité photocatalytique inférieure à 3,0 x 10?-3¿ cm?-1¿ min?-1¿ .plusmn. 2,0 x 10?-3¿ cm?-1¿ min?-1¿. Le substrat est un substrat en verre, y compris un substrat en verre tel qu'une feuille de verre ou qu'un ruban de verre flottant continu.
