  • Publication number: 20020031470
    Abstract: This invention provides mesostructured oxide ceramics and a synthesizing method thereof, the synthesizing method employs a water-based solvent containing a metallic salt or metal complex as the ceramics precursor, template formed from an organic compound or the association thereof, and a precipitant, wherein mesostructured oxide ceramics are obtained from self-assembled oxide ceramics and organic substance by directly extracting oxide ceramics at a low temperature of 200° C. or less by utilizing a homogenous precipitation reaction from said ceramics precursor under the coexistence of a nanometer-sized template in the solvent, and separating and collecting the obtained precipitation, and mesostructured oxide ceramics is prepared by employing the synthesizing method described above.

  • Patent number: 6207621
    Abstract: A surface of a given base material is hydrophilized by irradiating, for example, a vacuum ultraviolet light to itself. Then, on the surface is formed a monomolecular film made of a fluoroalkylsilane preferably having at least one of a long fluoroalkyl-chain and a long alkyl-chain which preferably have lengths of not less than 1 nm. Then, the base material and the monocular film are thermally treated and thereby a member having a high lubricative surface can be obtained which has strong couplings between the base material and the molecular film through a dehydrating condensation reaction.

  • Patent number: 5783260
    Abstract: A thin-film forming method comprising an uncured-layer forming step in which a mixed composition containing an organic polymerizing agent curable composition and a silicone polymerizing curable composition is prepared to form an uncured layer consisting of this mixed composition on a resin substrate; a solvent removing step in which the solvent in the uncured layer is removed; a first polymerization curing step in which the organic polymerizing curable composition in the uncured layer is polymerized; and a second polymerization curing step in which the silicone polymerizing curable composition in the uncured layer is polymerized. The thin-film forming method can comprise formation of the uncured layer on a resin substrate through the intermediation of a primer layer or formation of an uncured underlayer and uncured top layer followed by separate underlayer polymerization and top layer polymerization curing steps.
