  • Patent number: 9017773
    Abstract: A method is described for depositing nanostructures, such as nanostructures of conducting polymers, carbon nanostructures, or combinations thereof. The process comprises placing the nanostructures in a liquid composition comprising an immiscible combination of aqueous phase and an organic phase. The mixture is mixed for a period of time sufficient to form an emulsion and then allowed to stand undisturbed so that the phases are allowed to separate. As a result the nanostructure materials locate at the interface of the forming phases and are uniformly dispersed along that interface. A film of the nanostructure materials will then form on a substrate intersecting the interface, said substrate having been placed in the mixture before the phases are allowed to settle and separate.

  • Publication number: 20150111449
    Abstract: We report a method of preparation of highly elastic graphene oxide films, and their transformation into graphene oxide fibers and electrically conductive graphene fibers by spinning. Methods typically include: 1) oxidation of graphite to graphene oxide, 2) preparation of graphene oxide slurry with high solid contents and residues of sulfuric acid impurities. 3) preparation of large area films by bar-coating or dropcasting the graphene oxide dispersion and drying at low temperature. 4) spinning the graphene oxide film into a fiber, and 5) thermal or chemical reduction of the graphene oxide fiber into an electrically conductive graphene fiber. The resulting films and fiber have excellent mechanical properties, improved morphology as compared with current graphene oxide fibers, high electrical conductivity upon thermal reduction, and improved field emission properties.
