  • Graphite fibril material
    Publication number: 20040126307
    Abstract: A graphite fibril material comprised primarily of an aggregate of an average particle diameter of 0.1 to 100 &mgr;m in which-fibrils are intertwined, the fibrils being graphite fibrils of a fiber diameter of 0.0035 to 0.075 &mgr;m and spacing of the carbon hexagonal net plane as determined by the X-ray diffraction method of 3.36 to 3.53 angstroms.
    Type: Application
    Filed: June 20, 2003
    Publication date: July 1, 2004
    Applicant: Hyperion Catalysis International, Inc.
    Inventors: Hiroharu Ikeda, Paul R. Nahass, Robert Hausslein
  • GRAPHITE FIBRIL MATERIAL
    Publication number: 20020068033
    Abstract: A graphite fibril material comprised primarily of an aggregate of an average particle diameter of 0.1 to 100 &mgr;m in which fibrils are intertwinned, the fibrils being graphite fibrils of a fiber diameter of 0.0035 to 0.075 &mgr;m and spacing of the carbon hexagonal net plane as determined by the X-ray diffraction method of 3.36 to 3.53 angstroms. It is of high crystallinity and purity and is of superior conductivity, chemical stability, solvent absorption capacity and reinforcing capacity.
    Type: Application

  • High strength conductive polymers
    Patent number: 5651922
    Abstract: A polymeric composition having improved toughness and conductivity comprising carbon fibrils, at least a portion of which are in the form of aggregates, wherein, as measured on an area basis, substantially all of the aggregates are less than about 35 .mu.m in diameter. A polymeric composition having improved toughness and conductivity is prepared by combining carbon fibrils, at least a portion of which are in the form of aggregates, with a polymeric material, mixing the combination to distribute the fibrils in the polymeric material and applying shear to the combination to break down the aggregates until substantially all of the aggregates are less than about 35 .mu.m in diameter.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: July 29, 1997
    Assignee: Hyperion Catalysis International
    Inventors: Paul R. Nahass, Stephen O. Friend, Robert W. Hausslein
