The water/oil repellant coating film according to claim 1 , whereinthe water/oil repellant coating film is chemically bound with the surface of the solid object. An aspect of the present invention relates to manufacturing methods of water/oil repellent coating film and manufacturing methods of precursor solution thereof.Upon a droplet adhering to a surface of a solid object, corrosion, deterioration, and pollution may expand from the adhered point. For example, an exhaust pipe of an engine is continuously exposed to high temperature air. Meanwhile it is known that rusting is occurred from a point at which a water droplet is adhered if the water droplet is adhered or condensation is occurred when temperature of the exhaust pipe is low. Further, if oil adhered to a solid subject is continued to be exposed to high temperature air, the oil is carbonized and adheres with a high strength. Therefore, visibility may be decreased and choke may occur. Therefore, in various fields of engineering, material and surface treatment is tried to be developed, which makes it possible to prevent deterioration of capability for removing droplets over a long period of time even in a high-temperature environment.Recently, ...

The coatings in some embodiments possess a self-similar structure that combines a low-cost matrix with two feature sizes that are tuned to affect the wetting of water and freezing of water on the surface. Dewetting and anti-icing performance is simultaneously achieved in a structural coating comprising multiple layers, wherein each layer includes (a) a continuous matrix; (b) discrete templates dispersed that promote surface roughness to inhibit wetting of water; and (c) nanoparticles that inhibit heterogeneous nucleation of water. These structural coatings utilize low-cost, lightweight, and environmentally benign materials that can be rapidly sprayed over large areas using convenient coating processes.

The invention provides a dust repellant and anti-reflective inorganic coating and the method for preparing the coating. The dust repellant and anti-reflective inorganic coating includes nano-porous silica (SiO) network of about 5 nm to about 35 nm and is characterized by cracks. The method of preparing the dust repellant and anti-reflective inorganic coating on a substrate includes mixing of aqueous SiOsolution with a solvent. The aqueous SiOsolution with the solvent is stirred to form a solution. The solution is coated on the substrate to form a film on the surface of the substrate. Thereafter, the film is annealed by heating the film to a temperature of about 500° C. to about 700° C. within a period of about 2 minutes to about 2 hours. Finally, the film is allowed to cool down. 1. A dust repellant and anti-reflective inorganic coating comprising nano-porous silica network and silica nanoparticles of about 5 nanometer (nm) to about 35 nm , wherein the dust repellant and anti-reflective inorganic coating is characterized by cracks; andwherein the cracks are about 0.3 micrometer (μm) to about 3 μm in length and about 0.01 μm to 0.05 μm in width to impart an anti-reflective property to the coating.2. (canceled)3. A method of preparing a dust repellant and anti-reflective inorganic coating on a substrate , the method comprising:mixing aqueous silica (SiO2) solution with a solvent, wherein the silica is about 5 nm to about 35 nm in size;stirring the aqueous SiO2 solution with the solvent to form a solution;coating the solution on the substrate to form a film on the surface of the substrate;annealing the film by heating the film to a temperature of about 500 degree Celsius (° C.) to about 700° C. within a period of about 2 minutes to about 2 hours to create cracks about 0.3-3.0 micrometers (μm) in length and about 0.01-0.05 μm in width to impart an anti-reflective property to the film; andallowing the film to cool down.4. The method of claim 3 , wherein the substrate is ...
