Abstract
A carbon nanostructure producing method includes a growth step in which a plurality of catalyst particles in close contact with each other are separated in a flow of a carbon-containing gas so as to grow carbon nanotubes between the plurality of catalyst particles, and an elongation step in which the carbon nanotube is elongated by a wind pressure of the carbon-containing gas with at least one of the catalyst particles being retained.
Claims6
A carbon nanostructure producing method comprising:
- a growth step in which a plurality of catalyst particles in close contact with each other are separated in a flow of a carbon-containing gas so as to grow carbon nanotubes between the plurality of catalyst particles;
- and
- an elongation step in which the carbon nanotube is elongated by a wind pressure of the carbon-containing gas with at least one of the catalyst particles being retained,
- wherein the carbon nanotubes are attached to more than one of the plurality of catalyst particles at the same time.
