Abstract:
Embodiments of the present invention relate to transfer print circuitry. A conductive composition is applied to at least a portion of a first side of a first layer. A second layer is applied to at least a portion of the first side of the first layer in a manner that at least covers the conductive composition. The conductive composition comprises graphene sheets. The first layer is a release layer, a substrate, or an adhesive layer. The second layer is a release layer, a substrate, or an adhesive layer.
Abstract:
Embodiments of the present invention relate to energy storage devices and associated methods of manufacture. In one embodiment, an energy storage device comprises an electrolyte. An anode is at least partially exposed to the electrolyte. A selectively permeable membrane comprising a graphene based material is positioned proximate to the anode. The selectively permeable membrane reduces a quantity of a component that is included in the electrolyte from contacting the anode and thereby reduces degradation of the anode.

Compositions comprising graphene sheets. at least one reinforcing agent, and at least one rubber. The compositions may further comprise carbon black. The compositions may be formed into articles including tire components.
Abstract:
Compositions comprising graphene sheets, at least one aromatic compound. The compositions may optionally contain a polymer and/or acid catalysts. The may be in the form of inks or coatings. The aromatic compounds used in the present invention comprise at least one aromatic ring. They may comprise two or more aromatic rings. When two or more aromatic rings are present, they may be fused, bonded directly to each other, bonded using a spacer of one or more atoms, etc. The aromatic rings can be all-carbon based or can contain heteroatoms (heteroaromatics).

Abstract:
Thermal management devices comprising compositions comprising graphene sheets and compositions comprising graphene sheets and at least one thermally conductive, non-electrically conductive compound. The thermal management devices of the present invention comprise compositions comprising graphene sheets, and other components such as electrically conductive materials. By thermal management device is meant a device or component of a device that is designed or used to generate, spread, disperse, otherwise handle or manage the flow of heat. Examples include heaters, heating elements, heat sinks, thermal diffusion devices, heat spreaders, coolers, thermally conductive adhesives, thermally conductive gaskets and seals. The thermal management devices can be flexible and made to conform to surfaces. They can be crease resistant and thin. They can be used in items such as apparel, bags, gear, etc.
