    摘要： It relates to high purity single-walled carbon nanotubes having controlled diameter, useful as industrial materials, including high-strength carbon wire rods, particularly uniform single-walled carbon nanotubes having diameter fallen in a range of from 1.0 to 2.0 nm, and a method for producing the same efficiently, in large amount and inexpensively. The single-walled carbon nanotube obtained is characterized in that its diameter is fallen in a range of from 1.0 to 2.0 nm, and an intensity ratio IG/ID between G-band and D-band in a Raman spectrum is 200 or more. Furthermore, those single-walled carbon nanotubes are synthesized by a gas-phase flow CVD method that uses a saturated aliphatic hydrocarbon which is liquid at ordinary temperature as a first carbon source and an unsaturated aliphatic hydrocarbon which is gas at ordinary temperature as a second carbon source.

    摘要： Carbon nanotubes are produced by successively repositioning an axially extending rod-like carbonaceous anode relative to a cathode surface such that a tip end surface of the anode successively faces on different portions of the cathode surface while impressing a direct current voltage therebetween, so that an arc discharge occur with the simultaneous formation of carbonaceous deposits containing carbon nanotubes on each of the portions of the cathode surface. The carbonaceous deposits are scraped and collected. A device for carrying out the above method includes a driving member for displacing the cathode surface relative to the anode.

    摘要： A fine carbon fiber having an outer diameter of about 1 to about 80 nm and an aspect ratio of 10 to 30,000, comprising a hollow center portion and a multi-layer sheath structure of a plurality of carbon layers, the layers forming annual rings, wherein the sheath-forming carbon layers form an incomplete sheath, i.e., the carbon layers are partially broken or disrupted in a longitudinal direction, and the outer diameter of the carbon fiber and/or the diameter of the hollow center portion are not uniform in a longitudinal direction. The carbon fiber is obtained by instantaneously reacting a carrier gas at a high temperature and an organic compound gas kept at a temperature below the decomposition temperature of the transition metal compound and has a conductivity equivalent to that of a conventional vapor phase method and is useful as a filler material in resins, rubbers, paints and the like.
