Title:
MANUFACTURING METHOD OF MONOLAYER CARBON NANOTUBE AND ITS UNIT
Document Type and Number:
Japanese Patent JP3810756
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily remove impurity carbons such as carbon nano particle, amorphous carbon, etc., from the net-like deposit of a monolayer carbon nanotube by carrying out the formation and the refining of the monolayer carbon nanotube in the same reactor 10.
SOLUTION: In this manufacturing method of the monolayer carbon nanotube, in a reactor kept in the atmosphere of a mixed gas of H2 and Ar, an alternate current arc discharge A is generated between carbon electrodes 20R and 20L which are faced to the rectangular direction of the pipe axis, and the net-like deposit of a monolayer carbon nanotube is formed in the space connecting the carbon electrodes 20R and 20L and the inner wall of the reactor 10, then, the atmosphere of the reactor 10 is changed to a mixed gas of O2 and Ar, and the temperature inside of the reactor 10 is raised with a heating device 14, and the carbon nano particle, amorphous carbon , etc., are removed by gasification and the monolayer carbon nanotube of high purity can be obtained.
