  • Patent number: 8821773
    Abstract: Aspects of the invention are directed to a method for forming a graphene composite structure. Initially, an encapsulating film is formed on a substrate. The encapsulating film comprises graphene. Subsequently, a plurality of particles are deposited on the encapsulating film, and then a temporary layer is deposited on the plurality of active particles and the encapsulating film. The substrate is then removed. Lastly, the temporary layer is also removed so as to cause the plurality of particles to form a cluster that is at least partially encapsulated by the encapsulating film.

  • Patent number: 8808607
    Abstract: A thermally conductive sheet has cut surfaces with low surface roughness and hence shows reduced thermal resistance at the interfaces, and high thermal conductivity in the thickness direction. Thus, the thermally conductive sheet can be interposed between any of various heat sources and a radiation member. The process for producing the thermally conductive sheet includes at least: an extrusion molding step in which a thermally conductive composition containing a polymer, an anisotropic thermally conductive filler, and a filler is extruded with an extruder to thereby mold an extrusion-molded product in which the anisotropic thermally conductive filler has been oriented along the extrusion direction; a curing step in which the extrusion-molded product is cured to obtain a cured object; and a slicing step in which the cured object is sliced into a given thickness with an ultrasonic cutter in the direction perpendicular to the extrusion direction.
