  • Publication number: 20180112083
    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.

  • Publication number: 20180111160
    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.

  • Patent number: 9809492
    Abstract: The invention relates to a substrate (30) coated on one face (31) with a multilayer of thin films (34) comprising at least one metal functional layer (140) based on silver or made of silver and two antireflective coatings (120, 160), the said antireflective coatings each comprising at least one antireflective layer (124, 164), the said functional layer (140) being disposed between the two antireflective coatings (120, 160), characterized in that the said metal functional layer (140) is a discontinuous layer having a surface area occupation factor in the range between 50% and 98%, or even between 53% and 83%.

  • Patent number: 9371250
    Abstract: A process for forming an array of irregularities or features that are submicron-size in height and that have a characteristic lateral dimension that is micron- or submicron-size, over a surface of a material, by ion erosion, the process including: supplying the material with a thickness at least equal to 100 nm, the material being a solid hybrid material that includes: a simple oxide or a mixed oxide of one or more elements, an oxide molar percentage in the material being at least 40%; and a species, of a different nature to the one or more elements of the oxide, a molar percentage of the species in the material ranging from 6 mol % up to 50 mol % while remaining below the percentage of the oxide, most of the species having a largest characteristic dimension smaller than 50 nm, optionally heating the hybrid material before the erosion; structuring the surface of the hybrid material with an erosion that lasts less than one hour over an erosion area greater than 1 cm2, until the array of features is formed, the

  • Patent number: 8331026
    Abstract: The present invention relates to a process for surface structuring, that is to say, for meaning forming at least one array of patterns with a submillimeter scale characteristic lateral dimension on a flat surface of a product comprising a substrate bearing at least one layer resulting from a sol-gel process, where the structuring is done hot with a hydrolyzed sol layer based on alkoxides and/or halide(s) of at least one metal chosen among Si, Ti, Zr, W, Sb, Hf, Ta, V, Mg, Al, Mn, Co, Ni, Sn, Zn, and Ce with a nonreactive organic group, where the structuring is carried out by contact with a structured mask and exerting pressure as needed, and where the structuring is carried out in a temperature range suited for a sufficient condensation threshold ensuring the thermal hold of the structuring, with a total structuring time less than or equal to two hours. The invention also covers the resulting product.

  • Patent number: 7955687
    Abstract: The subject of the invention is the use of a material composed of a substrate equipped with a coating based on titanium oxide surmounted by a thin hydrophilic layer forming at least one part of the outer surface of said material and that is not composed of titanium oxide, as a material that prevents the deposition of mineral soiling on said outer surface in the absence of water runoff.
