  • Patent number: 10385189
    Abstract: The present invention provides a graphene composite powder form material that is suitable for industrialized application. The graphene composite powder form material is composited by graphene materials and a high-molecular compound. The high-molecular compound is uniformly coated on surfaces of the graphene material. Any adjacent graphene materials are separated by the high-molecular compound. An apparent density of the graphene composite powder form material is larger than or equal to 0.02 g/cm3. Under an external pressure, the graphene materials in the graphene composite powder form material do not re-stack, and can be easily restored to original form, which benefit the storage and transportation. Besides, the graphene composite powder form material has a good compatibility in other material systems, which greatly broadens the application fields in the downstream products and successfully solves the problem in industrial application.

  • Patent number: 10381539
    Abstract: One embodiment of a method for producing a plurality of nanostructures embedded in a host comprising the steps of: assembling a first preform, drawing said first preform into a first fiber, cutting said first fiber into a plurality of pieces, assembling said pieces of said first fiber into a second preform, and drawing said second preform into a second fiber. The host is made of a low thermal conductivity material such as a polymer or combination of polymers. The host can assume the form of a plurality of nanotubes which further reduces the host's thermal conductivity due to enhanced phonon scattering. The host can exhibit anisotropic thermal conductivity which reduces its thermal conductivity perpendicular to the direction in which it was drawn. The nanostructure-host composite can be cut into pieces and assembled into efficient thermoelectric devices for use in cooling or electric power generation applications. Other embodiments are described and shown.
