The present invention relates to an article having a surface coated with a nanostructured temporary super-hydrophobic film having a static contact angle with water of at least 140°, and comprising nanoparticles functionalized with a hydrophobic agent, wherein the functionalization of the nanoparticles with the hydrophobic agent has been performed before said nanostructured temporary super-hydrophobic film is coated on said surface. The surface of the article exhibits a static contact angle with water of less than 60° before being coated with the nanostructured temporary super-hydrophobic film. The treatment according to the invention can be used to provide an antirain function to optical articles having a hydrophilic surface.

A substrate having a superhydrophobic surface and methods of manufacturing the same and uses thereof. The substrate comprises a frame of a first material of interconnected structures exhibiting cavities having the shape of inverted pyramids; and a second material comprising hydrophobic structures filling the cavities, wherein the sidewalls of the inverted pyramids form an angle α of 105°<α<135° against the surface. The hydrophobic structures, such as nanoparticles, provide excellent water repellency, whereas the structures formed by a mechanically durable substrate material, typically comprising microstructures, act as armor to resist abrasion. The substrates are robust, durable and abrasion resistant and can be used as surfaces in self-cleaning, anti-fouling or heat transfer materials as well as in transparent surfaces, in particular in solar cells.

Compositions for treating a substrate to provide increased lubricity to portions of the substrate surface that come into contact with the surface of a mating component are provided. The treated substrates provide improved lubricity, while maintaining adhesion between the surface of the substrate and an overlying polymer coating and imparting corrosion resistance to the substrate surface. The compositions include a silanol coupling agent in combination with lubricating particles, and an acid, which are dissolved or dispersed in a mixture of organic solvent and water.

Chemically impregnated applicators used to provide hydrophobic surfaces on chemical mechanical polishing system components and related application methods. A method of forming a hydrophobic coating on a surface of a polishing system component includes cleaning the surface of the polishing system component to remove a polishing fluid residue therefrom and applying a hydrophobicity causing chemical solution to the surface of the polishing system component.

Although a composition for formation of a coating film is sometimes required to have satisfactory storage stability, it could not be said that a conventionally known composition has sufficient storage stability. It is an object of the present invention to provide a composition comprising an organosilicon compound which is excellent in storage stability. The present invention provides a composition comprising an organosilicon compound (A) represented by the following formula (a1), a metal compound (B) represented by the following formula (b1), a carboxylic acid compound (C), and an acid catalyst. ##STR00001##

Provided is a CNT film coated substrate in which CNT is fixed to a substrate using a click reaction, so that a CNT film is uniformly formed with a high density and adhesive strength between the CNT film and the substrate is excellent to have high stability to water or an organic solvent. In the case of the conventional CNT film which was manufactured by spin coating, most of CNT was peeled off in a washing process, but in the case of the CNT film coated substrate according to the present invention, a high-density uniform CNT film coated substrate may be manufactured even after washing, and reproducibility between substrates may be secured.

The present invention relates to an eco-friendly and simple super-hydrophobic coating method that does not use harmful substances and special equipment. Coating according to the present invention may be performed as a single process without special equipment, and because only eco-friendly materials are used, the coating material may be easily used and discarded. In addition, even a three-dimensional pipe or a heat-exchanger having a complex shape may be modified to have super-hydrophobicity by applying the present coating, and a super-hydrophobic metal filter may be manufactured and used for oil-water separation. As a result, the present coating method is eco-friendly, simple, and applicable to various substrates, so it has great potential for application in various industries.
