  • Patent number: 9561955
    Abstract: Disclosed is a graphene composite thin film composition composed of nano graphene platelets (NGPs) bonded by a graphene oxide binder, wherein the NGPs contain single-layer graphene or multi-layer graphene sheets having a thickness from 0.335 nm to 100 nm. The NGPs occupy a weight fraction of 1% to 99.9% of the total composite weight. The graphene oxide binder, having an oxygen content of 1-40% (preferably <10%) by weight based on the total graphene oxide weight, is obtained from a graphene oxide gel. The composite forms a thin film with a thickness no greater than 1 mm, but preferably no greater than 100 ?m and no less than 10 ?m. This composition has a combination of exceptional thermal conductivity, electrical conductivity, and mechanical strength unmatched by any thin-film material of comparable thickness range.

  • Patent number: 9553223
    Abstract: A method of aligning microwires includes modifying the microwires so they are more responsive to a magnetic field. The method also includes using a magnetic field so as to magnetically align the microwires. The method can further include capturing the microwires in a solid support structure that retains the longitudinal alignment of the microwires when the magnetic field is not applied to the microwires.

  • Patent number: 9460828
    Abstract: Disclosed is a graphene printed circuit pattern structure including a substrate excellent in electrical insulation and a graphene printed circuit layer provided on the substrate. The graphene printed circuit layer is electrically conductive and has a circuit pattern like an electrical circuit on the circuit board. The graphene printed circuit layer includes surface-modified nanographene platelets, a carrier resin and a filler. The ratio of the particle size of the filler to the thickness of the surface-modified nanographene platelet is 2-1000, and the surface-modified nanographene platelets are dispersed in the carrier resin. The filler is uniformly placed among the surface-modified nanographene platelets so as to enhance effective contact for the surface-modified nanographene platelets. The graphene printed circuit pattern structure provides excellent electrical properties and heat dissipation to achieve protection by preventing electrical elements from overheat.
