    Abstract: A superhydrophobic and self-cleaning surface including a substrate and a superhydrophobic layer. The superhydrophobic layer having a reacted form of octadecyltrichlorosilane. The octadecyltrichlorosilane is disposed on and crosslinked to a surface of the substrate via surface hydroxyl groups. The surface exhibits a rms roughness of 40 nm to 60 nm, a water contact angle of 155° to 180°, and a contact angle hysteresis of less than 15°. A method of preparing the substrate with a superhydrophobic and self-cleaning surface including treating a substrate with a plasma treatment, contacting the substrate with water or an alcohol to form an hydroxylated substrate, contacting the hydroxylated substrate with a solution of octadecyltrichlorosilane in an alkane solvent at a concentration in the range of 0.05 M to 0.3 M, and drying the solution on to the substrate under ambient air to form the superhydrophobic and self-cleaning surface on the substrate.

    Abstract: The present invention relates to an article whose surface has been at least partly sealed and to methods of its sealing, the sealing layer comprising a reactive melt layer and a coating layer. The invention provides a method of sealing at least part of the surface of an article, comprising the steps of: (a) applying a reactive melt layer based on polyurethane to at least one part of the surface of the article; (b) smoothing the reactive melt layer; and (c) applying a coating material to form a coating layer on the reactive melt layer, the coating layer being applied before the full curing of the reactive melt layer.

    Abstract: The present invention refers to a method for preparing a superhydrophobic surface on a solid substrate comprising the steps of (a) providing a solvent in the form of a pressurized fluid in a vessel, wherein the fluid exhibits a decrease in solvency power with decreasing pressure; (b) adding a hydrophobic substance to the solvent as a solute, which substance is soluble with the pressurized fluid and has the ability to crystallize/precipitate after expansion of the fluid, thereby obtaining a solution of the solvent and the solute in the vessel; (c) having at least one orifice opened on the vessel, thereby causing the pressurized solution to flow out of the vessel and depressurize in ambient air or in an expansion chamber having a lower pressure than within the vessel, the solute thereby forming particles; and (d) depositing the particles on the substrate in order to obtain a superhydrophobic surface. Hereby, a pressurized fluid which expands rapidly as a result of depressurization is used to prepare the superhydrophobic surface, thereby facilitating the preparation of the surface. Moreover, the invention refers to an arrangement for preparing a superhydrophobic surface on a substrate, a superhydrophobic film prepared by the method of the invention, and a substrate having deposited thereon the superhydrophobic firm.
