  • Publication number: 20100173099
    Abstract: Evaporation and condensation of carbon is effected by arc discharge between an anode formed of a carbon electrode and a cathode disposed facing the carbon electrode 2 in an inert gas atmosphere, and at the same time, the generated carbon nanotubes are dispersed into an inert gas and transported along with the inert gas through a transporting tube, and a jet of the inert gas containing the carbon nanotubes is emitted from a nozzle, thereby forming carbon nanotubes on a target substrate. This provides a carbon nanotube manufacturing method wherein carbon nanotubes are generated with a simple process, and the CNT patterning process is simplified by forming a carbon nanotube film on a substrate, thereby reducing costs.

  • Patent number: 7131886
    Abstract: A method of producing a fiber, comprising the steps of introducing catalytic particles originally formed in a particle-forming chamber into an arraying chamber together with a carrier gas, to cause the catalytic particles to become arranged on a substrate disposed in the arraying chamber. A next step includes growing fibers, each including carbon as a major component, based on the catalytic particles arranged on the substrate. The fibers grow by heating the catalytic particles arranged on the substrate in an atmosphere containing carbon.
