Abstract
A carbon nanotube manufacturing method is provided. In the carbon nanotube manufacturing method, carbon nanoparticles are dispersed in a strong acid solution and heated at a predetermined temperature under reflux to form carbon nanotubes from the carbon nanoparticles. The carbon nanotubes can be simply produced on a mass-scale at low costs by using the strong acid solution.
Claims6
A method for manufacturing carbon nanotubes, comprising:
- dispersing carbon nanoparticles in a form other than a carbon nanotube in a strong acid solution;
- and
- heating said strong acid solution at a predetermined temperature wherein said strong acid solution vaporizes and is returned under reflux with the dissociation of carbon atom bonds within said dispersed carbon nanoparticles and the agglomeration thereof to form and grow carbon nanotubes from said dispersed carbon nanoparticles.
