<P>PROBLEM TO BE SOLVED: To provide a composition of matter consisting carbon fibrils, in details, an assemblage of a multiplicity of a randomly oriented carbon fibrils having low bulk density and can be used for a substrate or medium for various industrial and scientific purposes. <P>SOLUTION: The composition of matter consists of a three-dimensional, macroscopic assemblage of a multiplicity of the randomly oriented carbon fibrils. The fibrils being substantially cylindrical with a substantially constant diameter, having c-axes substantially perpendicular to their cylindrical axis, being substantially free from pyrolytically deposited carbon and having diameter between about 3.5-70 nanometers, and the assemblage has relatively uniform physical properties along at least its one-dimensional axis and a bulk density of 0.001-0.50g/cc. <P>COPYRIGHT: (C)2004,JPO |
