METHOD FOR MANUFACTURING CARBON NANOTUBE

摘要

Carbon nanotubes oriented in one direction are efficiently and easily manufactured. The method is provided with a step of bringing a solution, which contains metal ions to be a catalyst for growing carbon nanotubes, into contact with crystalline metal oxide particles, and adhering the catalyst on the surfaces of the metal oxide particles; a step of growing carbon nanotubes on the surfaces of the metal oxide particles whereupon the catalyst is adhered, by a CVD method or a combustion method, and manufacturing metal oxide particles which support the carbon nanotubes grown parallel to a direction substantially vertical to the surfaces of the metal oxide particles; and a step of removing the metal oxide particles from the metal oxide particles supporting the carbon nanotubes.
