    摘要: The invention relates to an article superior in slipping a waterdrop down a surface of the article. The article has a substrate; and a functional layer formed on a surface of the substrate. The functional layer is chemically bonded to the surface of the substrate through siloxane-bonding. The article is prepared by a method including: (a) dissolving in a solvent (1) a silicone that is one of a first silicone having at an end a hydrolyzable functional group and a second silicone having at an end a hydrolyzable functional group and at the other end a fluoroalkyl group, (2) an acid, and (3) water, thereby to prepare a mixed liquid; (b) applying the mixed liquid to the surface of the substrate, thereby to form thereon a precursory layer; and (c) drying the precursory layer into the functional layer. In the preparation of the article, a silica precursor sol is optionally added to the mixed liquid. Alternatively, a combination of a silica precursor sol and a fluoroalkylsilane having at its end a hydrolyzable functional group is optionally added to the mixed liquid. Furthermore, an underlayer made from a hydrolyzable silicon compound may be provided between the substrate and the functional layer.
