  • Carbon material precursor, carbon material precursor composition containing the same, and method for producing carbon material using the same
    Patent number: 11001660
    Abstract: A carbon material precursor includes an acrylamide/vinyl cyanide-based copolymer which contains 50 to 99.9 mol % of acrylamide-based monomer unit and 0.1 to 50 mol % of vinyl cyanide-based monomer unit; a carbon material precursor composition includes the above-described carbon material precursor and at least one additional component selected from the group consisting of acids and salts thereof; and a method for producing a carbon material, includes subjecting the above-described carbon material precursor or the above-described carbon material precursor composition to thermal-stabilization treatment as necessary, followed by carbonization treatment.

  • Resin composite material
    Patent number: 9728294
    Abstract: A resin composite material includes: fine graphite particles including plate-like graphite particles, an aromatic vinyl copolymer which is adsorbed on the plate-like graphite particles, and which contains a vinyl aromatic monomer unit represented by the following formula (1): —(CH2—CHX)—??(1) (in the formula (1), X represents a phenyl group, a naphthyl group, an anthracenyl group, or a pyrenyl group, provided that these groups may have each a substituent), and at least one hydrocarbon chain which is bonded to the aromatic vinyl copolymer, and which is selected from the group consisting of alkyl chains, oligoolefin chains, and polyolefin chains.
