Title:
MANUFACTURING METHOD FOR CARBON NANOTUBE AGGREGATES
Document Type and Number:
WIPO Patent Application WO/2021/172077
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a manufacturing method for carbon nanotube aggregates, which makes it possible to efficiently produce high-quality carbon nanotubes aggregates. The present invention is a manufacturing method in which carbon nanotube aggregates are grown on a substrate having a catalyst on the surface. In the manufacturing method, a substrate is continuously transported using a transport unit for transporting the substrate, by screw rotation, in each of: a formation unit for performing a formation step in which a catalyst on the substrate is put in a reduction state; and a growth unit for performing a growth step in which carbon nanotube aggregates are grown. Moreover, when implementing the formation step and the growth step, gas environments in these steps are prevented from being mixed with each other while both steps are implemented.
