    摘要: A highly dense chemically adsorbed film is formed by repeating the alternate process of adsorption reaction and washing. Adsorption reaction is directed by contacting the substrate surface, which has or is given an alkali metal or a functional group, with a chemical adsorbent, having halosilyl or alkoxysilyl groups at the end of molecules. An unreacted chemical adsorbent is then washed away from the substrate surface. The alternate treatment of adsorption reaction and washing is repeated, thereby covalently bonding a chemically adsorbed film to the substrate surface. As a result, a chemically adsorbed film is formed in which stem molecules are directly or indirectly covalently bonded to the substrate surface via at least one element chosen from the group consisting of Si, Ge, Sn, Ti, Zr, S or C and graft molecules are covalently bonded to at least one element chosen from Si, Ge, Sn, Ti, Zr, S or C via at least one bond chosen from —SiO—, —GeO—, SnO—, —TiO—, ZrO—, —SO2—, —SO— and —C—.

    摘要: By forming a film that comprises a microcrystalline polymer having at least a fluorocarbon group and has a rough surface on a surface of a base material, super-water-repellency is provided, the dew condensation water of an air conditioner, for example, can be easily removed, and the freezing of the fin of the heat exchanger can be prevented. A fin that is made of aluminium is coated with a solution for forming a coating film, in which CF3(CF2)7—(CH2)2—SiCl3 is diluted with nonaqueous cyclohexamethyl trisiloxane at a concentration of 10 vol. % for preparation, to a thickness of 1 to 10 &mgr;m by a brush, and then the cyclohexamethyl trisiloxane is vaporized in an atmosphere having a relative humidity of about 75% at room temperature. CF3(CF2)7—(CH2)2—SiCl3 that remained on the fin is rapidly hydrolyzed with the moisture in the atmosphere, and the moisture in air and a —SiCl3 group dehydrochlorinated to form a microcrystalline polymer on the fin. As a result, a coating film having a surface roughness in the range of 1 to 40 &mgr;m and a contact angle of about 171° to water can be formed.

    摘要: A chemically adsorbed multilayer film is formed through the process of replacing a halogen atom on the surface of a chemically adsorbed film with an alkaline metal or changing the halogen atom to a Grignard group by Grignard reaction. This manufacturing method does not disrupt the molecules of the chemically adsorbed film, is easy to perform, low in cost and is safe. After replacing the halogen (for example, Br) on the surface of the film with an alkaline metal such as Li, a condensation reaction including a dealkalihalide reaction is promoted by contacting the chemically adsorbed film with an adsorbent, such as a chemical adsorbent--containing a halosilane group at one end of a molecule--dissolved in a nonaqueous solvent. A chemically adsorbed multilayer film is then formed by reacting the chemically adsorbed film with chemical absorption composition and with water after removing unreacted adsorbents using a nonaqueous solution.

    摘要: According to the invention, a fluorine-based or siloxane -based chemical adsorbed film containing a fluorocarbon compound can be formed on a given substrate surface in a laminated state and through chemical bonds (i.e., covalent bonds) with the substrate, it is possible to obtain a laminated film which has satisfactory adhesion to the substrate, is substantially pin-hole free and is very thin. Further, since the outermost layer may be substituted by fluorocarbon groups or hydroxyl groups, it is possible to obtain a film which has excellent water- and oil-repelling properties or hydrophilic and oil-repelling properties and can replace fluorine-based coating films, thus improving the performance of products requiring a coating having a water- and oil-repelling resistant property, weather-resistant property, wear-resistant property and so forth which are desirable in electric products, vehicles, industrial devices and so forth.
