METHOD FOR TEXTURING A SUBSTRATE HAVING A LARGE SURFACE AREA

摘要

The invention relates to a method for forming a texture on a substrate comprising: depositing a deformable layer on the substrate; bringing the deformable layer into contact with the textured surface of a secondary stamp; introducing the covered substrate and the secondary stamp into a bag made from non permeable material; introducing the bag and the contents thereof into a sealed chamber; removing the air from the chamber until a pressure value of at most 0.5 bar is obtained; sealing the bag before reintroducing air into the chamber; introducing the sealed bag and the contents thereof into an autoclave; applying a pressure of between 0.5 and 8 bar and a temperature of between 25 and 400 °C for a period of between 15 minutes and several hours; opening the bag; and separating the substrate and the secondary stamp. The invention also relates to: a transparent assembly comprising a glass substrate covered with a textured layer which is obtained using the above method; and the uses of the method in order to obtain a substrate intended for extracting guiding or redirecting light or a superhydrophobic or superhydrophilic substrate.
