Description of the invention: [Technical field to which the invention pertains] The manufacturing method, in particular, relates to a surface structure and a method for producing the same, relating to a surface structure and an aqueous surface thereof. [Prior Art] The demand for thinning and miniaturization of common household items has prompted all industries to enter the era of nanotechnology. On the other hand, humans expect to reduce the maintenance costs and improve the production of the products of the people's livelihood. The quality and self-cleaning (10)f_cleaning products are in line with this expectation, because the market demand for these products has increased significantly, and therefore The development of self-cleaning primary layer (or hydrophobic coating) materials has attracted much attention in the market. For example, the self-cleaning function of the building curtain glass, kitchen silk bath can maintain low cost f; application in solar cells, satellite antenna surface, automotive front glass = spalling coating can improve the quality and performance of the product; The hydrophobic coating on the outer shell of the Feiyuzhai can reduce fuel consumption and exhaust gas pollution caused by resistance. There are many studies on self-cleaning coatings or hydrophobic coatings. U.S. Patent No. 5,709,741 discloses a composition comprising 5 to 5 G% m (disii fine (tetra) derivative and at least one inorganic material selected from the group consisting of dioxo, carbonic acid 26 and magnesium oxide and taught to be applied to a glass substrate. Above, it can be hydrophobic ((4) water-based). f 6,458,420 job time* use the method of treating the glass surface with the two-stone nitrous oxide derivative to give the glass surface drainage. But in this two special shots, through various money correction Bio-surface treated glass, the contact angle of water droplets is only about 90. It is less than 12〇. The hydrophobicity is 18300P01 5 1291902 - still insufficient. Moreover, the adhesion between the hydrophobic layer and the substrate is insufficient. Under the roughening of the surface, a fluorine-based resin, a sulphur-burning coupler or a polymer such as a drainage agent is used (when the surface of the substrate is treated separately by water, the contact angle of the water droplet on the treated surface is also only about 9 Å. 120. The above hydrophobic properties. /There is also the application of the "bionic lotus effect" technique, which is to form a rough surface on the substrate, so that the air molecules are restricted to form an air cushion, and the surface of the low surface energy material is added. characteristic The contact angle of the water droplets of the coating material can be greater than 150, thereby reducing the adhesion of water droplets and oil droplets. Reviewing the technique of roughening the surface, using the lyophilized method, the coarsening or lithography of the physical hygiene table The remaining method has been carried out, but some of the above methods have the disadvantages of being expensive, costly, and difficult to mass produce. For example, U.S. Patent No. 5,514,424 discloses an increase in surface drainage of polymer products. In the method, the surface of the polymer is treated with an acid or a test to be roughened, and the treated surface is coated with a fluorine-based polymer obtained by plasma polymerization, thereby forming a surface of the polymer product. Superhydrophobic structure is formed. However, the plasma preparation method is expensive, and in addition, plasma polymerization usually requires high energy, and thus often causes deterioration of the polymer. Further, since the visible light wavelength is about 4 〇〇 nm, the general use is utilized. A rough surface layer made of micron-sized (1 OOOnm or more) particles, because the particle size is much larger than the wavelength of visible light, it blocks or interferes with the passage of visible light through the rough surface layer. An opaque or low-transparency problem. For example, US Patent No. 6, 〇 60, 521 discloses an aqueous dispersion comprising a particulate solid having a hydrophobic surface, up to about 30 〇/sterol, and water, wherein the alcohol is stored at 18300P01. 6 1291902 allows the granulated solid to form a dispersion in water, and after application to the substrate and after drying, retains the hydrophobic outer surface. However, the average particle size of the particles produced in this patent is about 3000 nm ( 3//m) is about the micron level, so that the transparency of the coating is poor. Similarly, the rough surface made by the sol gel technique or the plasma roughening method also has poor transparency. In other words, the world's countries in the self-cleaning coating structure design, the use of multi-layer composite structure to achieve super-hydrophobic self-cleaning function. However, to date, there is no self-cleaning coating that combines high transparency and superhydrophobicity. In addition, such self-cleaning coatings often have poor adhesion, insufficient hardness, and/or insufficient durability. SUMMARY OF THE INVENTION The purpose of this month is to provide a surface structure for forming a surface structure on a substrate, which has a high transparency and superhydrophobicity. Another object of the present invention is to provide a method of forming the surface structure of the substrate i so that the formed surface structure can be effectively adhered to the substrate. It is still another object of the present invention to provide a surface structure for forming on a substrate and being superhydrophobic. ^2Achieved the above and other objects. The method for forming a substrate structure provided by the present invention comprises: disposing a hydrophobic inorganic nanoparticle coating liquid on a substrate, and then (4) baking, # The package will be selected from the group consisting of cockroaches and cockroaches, and the resulting inorganic nephew dispersion, and (7) diclofenac derivative, in the presence of ammonium hydroxide. The substrate to which the method is applied is not particularly limited, but glass is better than 18300P01 7 1291902.
