摘要： The present disclosure provides advantageous graphene/graphite stabilized composites (e.g., graphene/graphite stabilized emulsion-templated foam composites), and improved methods for fabricating such graphene/graphite stabilized composites. More particularly, the present disclosure provides improved methods for fabricating pristine, graphene/graphite/polymer composite foams derived from emulsions stabilized by graphene/graphite kinetic trapping. In exemplary embodiments, the present disclosure provides that, instead of viewing the insolubility of pristine graphene/graphite as an obstacle to be overcome, it is utilized as a means to create or fabricate water/oil emulsions, with graphene/graphite stabilizing the spheres formed. These emulsions are then the frameworks used to make foam composites that have shown bulk conductivities up to about 2 S/m, as well as compressive moduli up to about 100 MPa and breaking strengths of over 1200 psi, with densities as low as about 0.25 g/cm3.

摘要： A method to fractionate and isolate components of oxidized graphene material is provided that includes fractionating a system that includes graphene oxide, a solvent and water, wherein the fractionation creates two phases or fractions: (i) a water phase or fraction that contains highly oxidized graphene oxide, and (ii) a solvent-in-water emulsion phase or fraction that contains a graphene-based material. The graphene-based material is recovered from the solvent-in-water phase or fraction. Fractionation of the solvent-in-water emulsion phase or fraction may be repeated. The graphene-based material (uGO) may be used in a range of applications, e.g., a medical device, a nanoelectronic, an electromechanical system, a sensor, a composite, a catalysis, and energy storage device, and an optics application.

摘要： Advantageous films and coatings (e.g., transparent conductive films), and improved methods for fabricating such films and/or coatings, are provided. The improved methods for fabricating transparent conductive films/coatings may involve trapping at least a portion of a layered material (e.g., graphene sheet(s) or layer(s) of graphite) at an interface of a phase separated system (e.g., at an interface of two non-mixing solvents). Transparent, one to four layer, conductive films/coatings of pristine natural flake graphene are produced by kinetically trapping graphene sheets at an interface of a phase separated system (e.g., at an oil/water interface).

摘要： The present disclosure provides advantageous composite films/coatings, and improved methods for fabricating such composite films/coatings. More particularly, the present disclosure provides improved methods for fabricating composite films by trapping at least a portion of a layered material (e.g., hexagonal boron nitride sheets/layers) at an interface of a phase separated system and then introducing the layered material to a polymer film. The present disclosure provides for the use of boron nitride layers to increase the properties (e.g., dielectric constant and breakdown voltage) of polymer films. The exemplary films can be produced by an advantageous climbing technique. Exemplary boron nitride films are composed of overlapping boron nitride sheets with a total thickness of about one nanometer, with the film then transferred onto a polymer film, thereby resulting in significant increases in both dielectric and breakdown properties of the polymer film.
