Methods and catalysts for the manufacture of carbon fibrils |
November 7, 2000 |
| An improved catalyst for producing carbon fibrils is made by incorporating an effective yield-enhancing amount of a carboxylate into a fibril-forming catalyst. Alternatively, such a catalyst is made by coprecipitating a compound of a metal having fibril-forming catalytic properties and a |

December 8, 1998 |
| A method of making randomly oriented carbons fibrils having a cylindrical constant diameter with c-axes perpendicular to their cylindrical axis, which are free of pyrolytically deposited carbon, with a diameter of between 3.5 and 70 nanometers, by dispersing carbon fibrils in a medium |

November 25, 1997 |
| It has now been found that highly advantageous three-dimensional, macroscopic assemblages of randomly oriented carbon fibrils can be prepared which have relatively uniform physical properties along one, preferably two and most desirably three-dimensional axis of the three-dimensional |

Carbon fibrils, method for producing same and adhesive compositions containing same |
November 26, 1996 |
| This invention concerns composite materials comprising a plurality of carbon fibrils in a matrix wherein the carbon fibrils are each characterized by a substantially constant diameter between about 3.5 to 70 nanometers and are substantially free of pyrolytically deposited thermal car |

Process for preparing composite structures |
October 22, 1996 |
| A compounding process for preparing a composite that includes introducing one or more fillers and a matrix material into a stirred ball mill and subjecting the fillers and the matrix material to a combination of shear and impact forces under reaction conditions including reaction time |

Carbon fibrils and method for producing same |
November 24, 1992 |
| The invention relates to carbon fibrils characterized by a substantially constant diameter, length greater than about 5 times the diameter, an ordered outer region of catalytically grown, multiple, substantially continuous layers of ordered carbon atoms having an outside diameter bet |
