  • Publication number: 20200192023
    Abstract: A high-density optical fiber ribbon is formed by two or more cladding-strengthened glass optical fibers each having an outer surface and that do not individually include a protective polymer coating. A common protective coating substantially surrounds the outer surfaces of the two or more cladding-strengthened glass optical fibers so that the common protective coating is common to the two or more cladding-strengthened glass optical fibers. A fiber ribbon cable is formed by adding a cover assembly to the fiber ribbon. A fiber ribbon interconnect is formed adding one or more optical connectors to the fiber ribbon or fiber ribbon cable. Optical data transmission systems that employ the fiber ribbon to optically connect to a photonic device are also disclosed. Methods of forming the cladding-strengthened glass optical fibers and the high-density optical fiber ribbons are also disclosed.

  • Publication number: 20190378773
    Abstract: An article including a glass or glass ceramic substrate, a noble metal layer, an adhesion promoting layer positioned between and bonded to the substrate and the noble metal layer, and a conductive metal layer positioned on and bonded to the noble metal layer. The adhesion promoting layer includes a siloxy group bonded with the substrate and a thiol group bonded to the noble metal layer. A method for manufacturing an article including applying an adhesion promoting layer comprising mercaptosilane to at least a portion of a glass or glass ceramic substrate, wherein siloxane bonds are formed between the mercaptosilane and the substrate, applying a noble metal layer to the adhesion promoting layer, the noble metal layer bonds with a thiol present in the mercaptosilane, thermally treating the noble metal layer, and applying a conductive metal layer to the noble metal layer.

  • Publication number: 20190363010
    Abstract: A method for bonding a conductive metal to an oxide substrate includes applying a porous coating to a surface of the oxide substrate, the porous coating including a porous oxide and catalyst nanoparticles dispersed therein, and depositing a conductive metal onto the porous coating. A portion of the conductive metal may be deposited within the pores of the porous coating to couple the conductive metal to the porous coating. Articles are also disclosed that include the oxide substrate, the porous coating coupled to a surface of the oxide substrate, and the conductive metal coupled to the porous coating. The porous coating may include a porous oxide and catalyst nanoparticles dispersed within the metal oxide. A portion of the conductive metal may be deposited within the pores of the porous coating to interlock the conductive metal to the porous coating.

  • Patent number: 10449473
    Abstract: The invention provides a coating which exhibits fast oleophobic-hydrophilic switching behaviour with, for example, equilibration of high oil contact angle (hexadecane=80°) and low water contact angle (<10°) values which occur within 10 s of droplet impact. These optically transparent surfaces display excellent anti-fogging and self-cleaning properties. The magnitude of oleophobic-hydrophilic switching can be further enhanced by the incorporation of surface roughness and in one embodiment the coating is applied to a surface in the form of a mesh in order to form an effective filter.

  • Publication number: 20190300718
    Abstract: Provided herein are articles including repellent coatings, as well as methods of making as using these articles. The articles can comprise a substrate and a repellent coating disposed on a surface of the substrate. The repellant coating can comprise hydrophobic particles dispersed within a polymer binder. The hydrophobic particles can be aggregated within the polymer binder, thereby forming a multiplicity of re-entrant structures embedded within and protruding from the polymer binder. The repellent coatings, and by extension the articles described herein, can exhibit selective wetting properties (e.g., superhydrophilicty/super-oleophobicity, or super-hydrophobicity/superoleophilicity).

  • Publication number: 20180118957
    Abstract: Articles including repellent surfaces and methods of making and using these articles are disclosed. The repellant surface can comprise a polymer having a roughened surface and a fluorinated silane and a lubricating liquid deposited on the roughened surface. The repellent surface, and by extension the articles described herein, can exhibit superomniphobic properties. The methods for producing the repellant surface can comprise dissolving a polymer in a solvent to produce a polymer solution and optionally adding a non-solvent to the polymer solution to produce a casting mixture. The polymer solution or casting mixture can be deposited on a surface of a substrate and the solvent and/or the non-solvent evaporated to provide a coated-substrate having a roughened surface. A functional layer comprising a fluorinated silane followed by a lubricating liquid can be deposited on the roughened surface to form the repellant surface.

  • Publication number: 20170056834
    Abstract: Multilayer coatings, articles comprising multilayer coatings, and methods of making and using thereof are described herein. The multilayer coating can contain two or more oppositely charged alternating layers, comprising at least one fixed layer comprising a first polymer and at least one inorganic layer comprising a plurality of particles, wherein the inorganic layer forms a surface of the two or more oppositely charged alternating layers. The multilayer coating can further contain an adhesion layer disposed on the at least one inorganic layer, the adhesion layer comprising a second polymer having a charge opposite that of the plurality of particles. The multilayer coating can also contain a functional layer disposed on the adhesion layer, wherein the functional layer forms a surface of the multilayer coating. In some embodiments, the coatings can separate a liquid mixture comprising a polar liquid and a non-polar liquid.
