  • Patent number: 9085487
    Abstract: The present invention describes a chemical vapor-phase deposition for carbon nanotube synthesis in which cement clinker is used as a ceramic matrix for anchoring transition-metal nanoparticles. Using cement clinker as nanoparticle anchoring base of transition metals allows carbon nanotubes to be generated on cement clinker particles and grains, in this way producing a kind of cement that is nanostructured with carbon nanotubes. By this process, the carbon nanotube synthesis and integration to clinker are carried out in just one continuous and large-scale stage. The process described herein can be applied to conventional cement industry whose production may be rated as tons per day. The present invention also proposes—as part of the carbon nanotube synthesis on cement clinker—several enrichment alternatives of cement clinker by using transition metals for producing such nanostructured composite, which may or not be integrated to the conventional cement industry.

  • Patent number: 9011727
    Abstract: Blending an electrically active, anodically coloring, electrochromic polymer with a non-electrochromic, non-electrically conductive binder polymer greatly enhances the performance of the anodically coloring, electrochromic polymer in an electrochromic device over time. In addition to improved physical characteristics of the blend, e.g., film build, durability etc, the coloristic properties, including color space and color strength, of the device comprising the blend are more durable than when using the neat polymer, and in certain instances, the color space and color intensity provided by the blend is superior to that available from the neat polymer.

  • Publication number: 20150099180
    Abstract: Surface-modified carbon hybrid particles may be characterized by a high surface area and a high mesopore content. Surface-modified carbon hybrid particles may be in agglomerated form. Surface-modified carbon hybrid particles may be used, for example, as conductive additives. Dispersions of such compounds in a liquid medium in the presence of a surfactant may be used, for example, as conductive coatings. Polymer compounds filled with the surface-modified carbon hybrid particles may be formed. Surface-modified carbon hybrid particles may be used, for example, as carbon supports.

  • Patent number: 8980136
    Abstract: A polymer composite composed of a polymerized mixture of functionalized carbon nanotubes and monomer which chemically reacts with the functionalized nanotubes. The carbon nanotubes are functionalized by reacting with oxidizing or other chemical media through chemical reactions or physical adsorption. The reacted surface carbons of the nanotubes are further functionalized with chemical moieties that react with the surface carbons and selected monomers. The functionalized nanotubes are first dispersed in an appropriate medium such as water, alcohol or a liquefied monomer and then the mixture is polymerized. The polymerization results in polymer chains of increasing weight bound to the surface carbons of the nanotubes. The composite may consists of some polymer chains imbedded in the composite without attachment to the nanotubes.

  • Patent number: 8961834
    Abstract: An electrically conductive thermoplastic composition is prepared by melt blending a polymer and a masterbatch of carbon nanotubes in wax having a melting point of about 45 to about 150° C. The masterbatch of carbon nanotubes in wax is more easily prepared than a conventional carbon nanotube masterbatch in high molecular weight polymer. Use of the masterbatch of carbon nanotubes in wax also improves the melt flow properties of the electrically conductive thermoplastic composition.

  • Patent number: 8956556
    Abstract: The present application is directed to dielectric isolators for use in aircraft fuel systems to control lightning induced current and allow dissipation of electrostatic charge. The dielectric isolators are configured to have a high enough impedance to limit lightning currents to low levels, but low enough impedance to allow electrostatic charge to dissipate without allowing buildup. Although the dielectric isolators may develop a potential difference across the dielectric length due to the effects of lightning currents and its inherent impedance, they are configured to withstand these induced voltages without dielectric breakdown or performance degradation. In one embodiment, the dielectric isolator includes a tube constructed of a composition including a thermoplastic organic polymer (e.g., PEEK) and carbon nanotubes, and a pair of fittings attached to opposing ends of the tube.
