摘要： PROBLEM TO BE SOLVED: To provide an organic/inorganic composite gradient material whose composition continuously varies in the thickness direction and which is useful in various applications as a new functional material. SOLUTION: An organic/inorganic composite gradient material comprises a composite in which an organic polymer compound and a metallic compound have been chemically bonded and has a structure in which the content of the metallic compound continuously varies in the direction from the depth of the material to its surface. A method of preparing the organic/inorganic composite gradient material comprises forming a coated film composed of a specific organic/inorganic composite film-forming coating solution on an organic substrate and drying the resulting film with heating. A film-forming coating material is composed of the organic/inorganic composite gradient material. An article is coated with the film-forming coating material.

摘要： PURPOSE:To prevent the generation of the damage and unequal orientation of oriented films by movement of spacers and the low-temp. foaming of a liquid crystal display device by coating the spacers with a fluororesin having a m. p. of a specific temp. or above at a thickness at which the ratio of the film thickness of the fluororesin layer/the grain size of silica particulates attains a specific range. CONSTITUTION:The silica particulates are coated with the fluororesin of >=200 deg.C m.p. at such a thickness that the ratio of the film thickness of the fluororesin layer/the grain size of silica particulates attains 1/100 to 1/3. An epoxy resin is usually cured at 160 to 200 deg.C and, therefore, the resin layer between the spacers and substrates flows out and the effect of preventing low-temp. foaming is lost when the epoxy resin melts in this temp. range. The fluororesin layer is compressed and deformed and the area of the contact parts of the silica particulates and the glass substrates widened, by which the movement of the spacers by vibration of ultrasonic waves used at the time of injecting liquid crystals or in a washing stage is prevented in a stage for controlling the gap of the liquid crystal panel in the range where the coating thickness of the fluororesin coating layer is 1/100 to 1/3 the grain size of the silica particulates.

摘要： PURPOSE:To provide a conductive particulate with excellence in particulate-diameter accuracy and without any electric defect by forming a coat layer, comprising partially deoxidized titanic oxide contained therein, on the surface of a spherical particulate made of a metallic oxide. CONSTITUTION:Spherical particulates (particulate diameter ranging from 0.5mu to 30mu) each made of a metallic oxide (silica or the like) are dispersed in an alcoholic group solvent consisting mainly of middle-class alcohol (butanol or the like), and then an aqueous solution of alkali (ammonium or the like) is added to the resultant solvent so as to activate the surface of each of the spherical particulates. A titanium compound (titanium tetrabutoxide) whereby titanic oxide can be formed is then added to the particulates-dispersed solution so as to be hydrolyzed, so that a titatic oxide coat layer(film thickness ranging from 0.01mu, to 1mu) may be formed on the surface of the spherical particulate. The coat layer is baked at a temperature ranging from 800 deg.C to 1,000 deg.C in a deoxidizing atmosphere (hydrogen gas) and/or in a nitriding atmosphere (nitrogen gas), so that a coat layer, comprising partially deoxidized titanic oxide of conductivity and/or titanium nitride contained therein, may be finally formed on the surface of the particulate. This process provides conductive particulate with highness in both strength and hardness, and also without any condensation.

摘要： PURPOSE:To obtain fine silica particles, coated with zirconia and suitable as reinforcing materials by coating the surfaces of fine spherical silica particles with zirconia. CONSTITUTION:Fine spherical silica particles are homogeneously dispersed in a solvent and a zirconium alkoxide is then added to the resultant dispersion and hydrolyzed to carry out dehydrating condensation of the produced hydrolyzate with OH groups on the surfaces of the fine spherical silica particles. Thereby, zirconia layers are formed. Since the fine spherical silica particles preferably have a monodisperse-particle diameter distribution, fine spherical particles synthesized from a silicon alkoxide are preferred. The zirconium alkoxide is not especially limited, if it is capable of undergoing hydrolysis in an aqueous solution and producing an oxide. Zirconium alkoxides homogeneously mixing with a solvent alcohol at about ambient temperature, e.g. zirconium tetra-n-propoxide and zirconium tetra-n-butoxide, however, are preferred.

摘要： PROBLEM TO BE SOLVED: To obtain silica fine particles having high hardness and strength as a whole which can function as a spacer for a long time when the particles are used as a spacer for a liquid crystal display device by applying a vinyl silane coupling agent on the surface of calcined silica fine particles and then forming a thermoplastic resin coating film having a single layer or multilayer structure thereon. SOLUTION: The resin-coated silica fine particles are produced by applying a silane coupling agent having vinyl groups on the surface of calcined silica fine particles and then forming a thermoplastic resin film having a single layer or multilayer structure thereon. The production method of the resin-coated silica fine particles includes the following processes (A) and (B). In the process (A), calcined silica fine particles are subjected to surface treatment with a silane coupling agent having vinyl groups so as to introduce vinyl groups to the surface of silica fine particles. In the process (B), unifunctional vinyl monomers are dispersed and polymerized in a polar solvent in the presence of a dispersion stabilizer, radical polymn. initiator and chain-moving agent to form a thermoplastic resin coating film on the surface of silica fine particles after the surface treatment.

摘要： PURPOSE: To obtain spherical particles with insulating films having dense and thick insulating films which are suitable as a spacer for a liquid crystal display device. CONSTITUTION: Spherical particles of metal oxide are dispersed in an alcohol solvent essentially comprising medium alcohol to obtain a dispersion liquid of particles. An alkali soln. is added to the dispersion liquid to activate the surface of particles to form a titanium oxide film on the particle surface. Thus, spherical particles with titanium oxide films (A) are obtd. Then the particles (A) are dispersed in an alcohol solvent essentially comprising medium alcohol to obtain a dispersion liquid, to which an alkali soln. is added to activate the surface of the titanium oxide film. Then silicon alkoxide or its partial hydrolyzed material (C) is added to perform hydrolysis, dehydration and condensation to obtain spherical particles with titanium oxide films and silica films (B). The obtd. particles (B) are separated from the dispersion liquid (process a). The particles (B) are dispersed in a lower alcohol solvent, to which quaternary ammonium salt as an electrolyte is added and dissolved. Then an alkali soln. and (C) are added to perform hydrolysis, dehydration and condensation to form further silica films, on the particles (B) (process b).
