Title:
METHOD FOR PRODUCING CARBON NANOTUBE STRAND WIRE AND CARBON NANOTUBE STRAND WIRE PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/026950
Kind Code:
A1
Abstract:
This method for producing a carbon nanotube strand wire includes: a first step in which a carbon-containing gas is supplied from one first end section of a tubular carbon nanotube synthesis furnace and a carbon nanotube is grown from each of a plurality of catalyst particles in a suspended state inside the carbon nanotube synthesis furnace to thus synthesize a plurality of carbon nanotubes; a second step in which the plurality of carbon nanotubes are assembled by aligning along the length direction of the carbon nanotubes in a first flow channel provided inside the carbon nanotube synthesis furnace to thus form a carbon nanotube strand wire; and a third step in which the carbon nanotube strand wire is recovered from a second end section, which is opposite to the first end section, of the carbon nanotube synthesis furnace, using a recovery gas flow that flows in a direction of separation from the carbon nanotube synthesis furnace.
