Title (EN) ROBUST SUPERHYDROPHOBIC MATERIAL AND COATING
(FR) MATÉRIAU ET REVÊTEMENT SUPERHYDROPHOBES ROBUSTES
Abstract:
(EN) The invention provides a composition for forming a hydrophobic material, the composition being made by combining: a perfluorinated amine compound comprising at least two amine moieties, such as a compound made by combining a straight or branched chain C1-10 alkyl amine having at least two amine groups per molecule, with a straight or branched chain C1-12 perfluorinated carboxylic acid contining at least one -COOH group per molecule; an epoxy compound comprising at least two epoxy moieties; a lubricant, such as a perfluorinated polyether; a population of nanoparticles; and a solvent. Hydrophobic materials formed by evaporation of the solvent from such a composition are also provided as are intermediates excluding the lubricant which are used in the formation of such compositions. Such compositions are used in the formation of hydrophobic and particularly superhydrophobic surfaces. Advantageously these compositions are useful to form robust surface coatings that are resistant to mechanical wear.
(FR) L'invention concerne une composition destinée à former un matériau hydrophobe, la composition étant produite par combinaison : d'un composé amine perfluoré comprenant au moins deux fractions amine, tel qu'un composé produit par combinaison d'une amine alkyle en C1-10 à chaîne droite ou ramifiée présentant au moins deux groupes amine par molécule, avec un acide carboxylique perfluoré en C1-12 à chaîne droite ou ramifiée contenant au moins un groupe -COOH par molécule ; un composé époxy comprenant au moins deux fractions époxy ; un lubrifiant, tel qu'un polyéther perfluoré ; une population de nanoparticules ; et un solvant. L'invention concerne également des matériaux hydrophobes formés par évaporation du solvant à partir d'une telle composition, ainsi que des intermédiaires, à l'exclusion du lubrifiant, qui sont utilisés dans la formation de telles compositions. De telles compositions sont utilisées dans la formation de surfaces hydrophobes, et en particulier superhydrophobes. Avantageusement, les compositions sont utiles en vue de former des revêtements de surface robustes qui résistent à l'usure mécanique.
