2. Description of the Related Art Conventionally, the surface of an inorganic material as described above is treated to impart water repellency (here, for convenience, the word "water repellency" is used even when repelling liquids other than water) and non-adhesiveness. Therefore, various surface treatment agents are used. For example, in plastic molding, a surface lubricant or a release agent is applied to a molding tool in order to make it slippery and prevent sticking by interposing it between the molding tool and a molded product. Commonly used are fatty acid soap, metal soap, paraffin wax, hydrocarbon oil, aliphatic alcohol, low molecular weight polyethylene, silicone resin and the like. Such substances are also widely used as water repellents. However, since such a surface treatment agent is difficult to apply thinly, it has to be applied fairly thickly in order to obtain sufficient water repellency and non-adhesiveness, and also has poor adhesion to the substrate, and The application work is also complicated. Similarly, Teflon (trade name of EIdu Pont Co.) coating, which has recently been attracting attention, has excellent non-adhesiveness, but is troublesome to handle and becomes a thick film.

Problems to be Solved by the Invention As can be understood from the above, conventional surface treatment agents for imparting water repellency and non-adhesiveness require complicated coating work such as coating, and a formed film is considerably Since it becomes thick, it cannot be used particularly for microfabrication, and the coating film is easily peeled and broken, so that handling is troublesome. The present invention aims to solve these problems and provide a more useful surface treatment agent.

It has been found that a desired surface treatment agent can be provided.

The surface treatment agent according to the present invention has two opposite parts, a hydrophilic part and a hydrophobic part. As shown in the above general formula, one of the structures of the surface treatment agent has a hydrophilic portion such as an isopropoxy group and an ethylene glycol residue, and therefore, the surface treatment agent has the same hydrophilicity as that of the inorganic material. It ensures a chemical bond with the surface. Further, the other part of the structure of the surface treatment agent has a hydrophobic part, that is, a fluorocarbon chain, and when the hydrophilic part is bonded to the surface of the inorganic material, the hydrophilic part faces outward. As a result of forming a coating film having a C—F bond on the surface of an inorganic material in this way, a low energy surface is imparted to the inorganic material, and thus a water-repellent and non-adhesive surface is obtained.

The formation of the coating film of the surface treatment agent is a simple method, for example, a small amount of the selected surfactant is dissolved in a solvent such as chloroform, trichloroethylene or the like to a treatment bath obtained by immersing the inorganic material to be treated for a short time, And it can be easily implemented by drying.

In the surface-treating agent of the present invention, the hydrophobic portion of the fluorocarbon chain will basically give a sufficiently low energy surface even with only C-F bonds (ie, n = 1) only at the ends. However, according to the study by the present inventors, if there is a C—F bond even in a portion slightly inside the surface of the film, that is, if n = 4, more preferable water repellency and tackiness are obtained. Can be achieved. In this case, it is possible to allow the presence of hydrocarbon chains in place of the fluorocarbon chains to be additionally included. In the present invention, this is the spacer Y
(See the previous equation).
