  • Robust superhydrophobic material and coating
    Patent number: 12703800
    Abstract: 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 confining 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.
