Title:
METHOD FOR PRODUCING CARBON NANOTUBE STRAND WIRE AND CARBON NANOTUBE STRAND WIRE PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/181692
Kind Code:
A1
Abstract:
The method for producing a carbon nanotube strand wire of the present disclosure is a method for producing a carbon nanotube strand wire provided with a first step for growing carbon nanotubes from each of a plurality of catalyst particles by supplying carbon-containing gas to a plurality of suspended catalyst particles within a tubular carbon nanotube synthesis furnace to obtain a plurality of carbon nanotubes and a second step for aggregating the plurality of carbon nanotubes to obtain a plurality of carbon nanotube strand wires, in which the second step is provided with a step 2A for orienting and aggregating a first carbon nanotube group composed of some of the plurality of carbon nanotubes along the longitudinal direction of the carbon nanotubes within a first flow path to obtain a first carbon nanotube strand wire and a step 2B for orienting and aggregating a second carbon nanotube group composed of some of the carbon nanotubes different from the plurality of carbon nanotubes that compose the first carbon nanotube group along the longitudinal direction of the carbon nanotubes within a second flow path to obtain a second carbon nanotube strand wire.
