Title:
MANUFACTURING METHOD AND MANUFACTURING DEVICE FOR CARBON NANOTUBE
Document Type and Number:
WIPO Patent Application WO/2022/202964
Kind Code:
A1
Abstract:
[Problem] To provide a carbon nanotube manufacturing method and manufacturing device capable of manufacturing a carbon nanotube with a high yield. [Solution] A first manufacturing device 100 primarily comprises a mass flow controller 110, a growth furnace 120, a quartz tube 130, a pressure gauge 150, an electromagnetic valve 160, a pressure adjustment valve 170, and a needle valve 180. The quartz tube 130 is a cylindrical tube comprising quartz, and is inserted into the growth furnace 120. The interior of the growth furnace 120 can be adjusted to a temperature suitable for the thermal decomposition temperature of each raw material resin. The pressure gauge 150 is connected to an outlet pipe 104 extending from an outlet end of the quartz tube 130. The electromagnetic valve 160 receives a pressure value from the pressure gauge 150, and opens/closes a pipe 106 in accordance with the pressure value. The raw material resin 144 is installed near an inlet end of the growth furnace 120. A catalyst metal 142 is installed at a position separated by a prescribed distance from the inlet end of the growth furnace 120.
