    Abstract: A film formation device (10) that increases the mechanical resistance of the liquid repellent film formed on the oxide film. The film formation device (10) includes an oxide film formation unit (14, 15, 16), which forms an oxidized film on a substrate by releasing grains towards the substrate that is rotated in a vacuum chamber (11), and forms an oxide film on the substrate by emitting oxygen plasma towards the oxidized film. A vapor deposition unit (17) vapor-deposits a silane coupling agent, which contains a hydrolytic polycondensation group and a liquid repellent group, on the oxide film. A polycondensation unit (20) polycondenses the silane coupling agent by supplying water towards the oxide film on the rotated substrate. The polycondensation unit supplies water to the oxide film before the vapor deposition unit vapor deposits the silane coupling agent on the oxide film.

  • Patent number: 9011710
    Abstract: Methods are disclosed for synthesizing nanocomposite materials including ferromagnetic nanoparticles with polymer shells formed by controlled surface polymerization. The polymer shells prevent the nanoparticles from forming agglomerates and preserve the size dispersion of the nanoparticles. The nanocomposite particles can be further networked in suitable polymer hosts to tune mechanical, optical, and thermal properties of the final composite polymer system. An exemplary method includes forming a polymer shell on a nanoparticle surface by adding molecules of at least one monomer and optionally of at least one tethering agent to the nanoparticles, and then exposing to electromagnetic radiation at a wavelength selected to induce bonding between the nanoparticle and the molecules, to form a polymer shell bonded to the particle and optionally to a polymer host matrix. The nanocomposite materials can be used in various magneto-optic applications.

    Abstract: A method is provided for the wet surface treatment of titanium dioxide, in order to produce durable universal grade titanium dioxide rutile pigment with superior optical properties. The method is characterized in that, a hydrous zirconia and silica composite layer is co-precipitated at acidic pH. Then, a layer of alumina is precipitated under a range of pH required for complete precipitation above the initial composite layer. The upper pH limit of the slurry during the alumina precipitation can be well controlled to avoid any chance for dissolution or damage of the composite zirconia-silica layer formed. Zirconia-silica composite layers and alumina thus precipitated advantageously improve the competence of the layers formed over a TiO2 base and provide improved durability with superior optical performance. The total surface treatment cycle time and chemicals used are minimal compared to conventional methods. Improvements in throughput and washing efficiency are also realized.

  • Patent number: 8728502
    Abstract: This disclosure is directed to a black effect pigment and a method of forming said pigment. The pigment comprises a platy substrate coated with SnO2 and/or SnO2 hydrates and Fe3O4 with an optional coating of metal oxides such as SiO2, TiO2, ZrO2 and ZnO2. The deposition of the SnO2 and/or SnO2 hydrates onto the substrate improves the adhesion and prepares the substrate surface for deposition of the iron oxides onto the platy surface, especially mica surfaces. While the pigment may be used in such applications as coating, powder coating, printing ink, plastic, ceramic material, glass, cosmetic formulation, laser marking pigment, pigment composition or dry preparation, the pigment is especially suitable for cosmetic applications.

  • Publication number: 20140120255
    Abstract: A method of plating a metal on a hydrophobic polymer, especially in the shape of small particles, involves: (a) contacting a surface of hydrophobic polymer substrate with a polycation such as poly(allylamine hydrochloride) to create a treated surface; (b) contacting the treated surface with a catalyst; and then (c) immersing the surface in a electroless metal plating bath to create a coating of metal on the surface. Metals include copper, silver, gold, nickel and cobalt. Catalysts are selected from compounds containing palladium, platinum, tin, copper, or nickel salts. Damaging surface treatments such as etching by plasma or acid are avoided.

  • Publication number: 20140113813
    Abstract: An irreversible thermochromic ink composition can include thermochromic pigment capsules dispersed in a carrier. The irreversible thermochromic pigment capsules can include an inner core having a color changing dye, a color activator for activating the color changing dye, and a wax, an outer core surrounding the inner core and comprising a color destroying agent, and a shell surrounding the outer core. Alternatively, the irreversible thermochromic pigment capsules can include an inner core having a color destroying agent and a wax, an outer core surrounding the inner core and comprising a color changing dye and a color activator for activating the color changing dye, and a shell surrounding the outer core. Written marks made with the irreversible thermochromic inks can be rendered a different color or substantially colorless by application of a sufficient amount of heat to melt or substantially liquefy the wax in the irreversible thermochromic pigment capsules.

  • Patent number: 8697185
    Abstract: A new device and process for continuously applying coatings, such as resin and additives or polymers or the like, to minerals are disclosed. The device and apparatus differ substantially from standard batch coating processes currently used by industry. The apparatus uses a horizontal cylinder with an internal auger and a series of injection ports distributed along the cylinder. Minerals that are to be coated are pretreated and passed through the mixing cylinder using the auger (which may comprise one or more screws with variable pitch blades). As the mineral particles pass through the cylinder various coating materials are injected by the injection ports. The complete system is described, the method of use is explained and the control system which allows for different products is described.

The cluster of particles comprises a plurality of particles with each particle in the plurality of particles contacting one or more other particles in the plurality of particles. Subsequently, one or more layers are deposited on the cluster of particles with the one or more layers comprising graphene. The plurality of particles are then etched away without substantially etching the deposited one or more layers. Lastly, the remaining one or more layers are dried. The resultant graphene structures are particularly resistant to the negative effects of aggregation and compaction.
