Abstract: A vehicle glazing includes on its surface to be exposed to the exterior atmosphere, at least in a zone not wiped by the windscreen wipers, a mineral oxide layer of 0.1 to 20 ?m thickness, 30 to 90% of the volume of which consists of 20 to 300 nm open pores that are distributed uniformly throughout the thickness of the layer, and almost all of which are connected to one another, the internal and external surface of the layer being functionalized with a compound containing a perfluoroalkyl or alkyl functional group, then saturated with a hydrophobic oil that impregnates the functionalized porous layer and forms a film on the surface thereof, the at least one zone being located facing a detecting device such as an anti-collision/obstacle-detecting/security video camera, or similar, placed in the interior of the vehicle, in particular on the face of the glazing.

Abstract: The invention relates to a cylindrical tube made of polymer material or glass, whose cylindrical inner wall includes a coating of hydrophobic particles having a surface with a peak-to-valley distance of between 100 nm and 50 ?m; a process for manufacturing said tube by forming a coating on its inner wall including the steps of displacing a segment of a liquid composition of suspended coating particles within the tube at a constant controlled velocity of at least 2 cm/sec so as to drive a homogeneous liquid film on the inner wall of the tube, letting the solvent of the liquid composition evaporate and the suspended coating particles deposit on the inner wall of the tube, optionally, repeating the two previous steps at least once.

Abstract: The invention relates to a method for forming a coating in the inner wall of a tube, including the following operations: moving a segment of a liquid composition of coating particles in suspension inside the tube at a constant controlled speed at least equal to 2 cm/s, so as to drive a homogeneous liquid film over the inner wall of the tube, and allowing the solvent of the liquid composition to evaporate and the coating particles in suspension to be deposited on the inner wall of the tube.

Abstract: The invention relates: to a process for forming a texture on a substrate, comprising: depositing a deformable layer on the substrate; bringing this deformable layer into contact with the textured face of a daughter stamp; introducing the coated substrate and the daughter stamp into a pouch made of an impermeable material; introducing the pouch and its contents into a hermetic vessel; evacuating air from the vessel until a pressure at most equal to 0.5 bar is reached; sealing the pouch before reintroducing air into the vessel; introducing the sealed pouch and its contents into an autoclave; applying a pressure comprised between 0.5 and 8 bar and a temperature comprised between 25 and 400° C.
