Abstract
A method of vertically aligning carbon nanotubes, whereby carbon nanotubes are grown on a substrate on which a catalyst metallic layer is formed, the grown carbon nanotubes are separated from the substrate in a bundle shape, the separated carbon nanotube bundles is put in an electrolyte having a charger, the carbon nanotube bundles are mixed with the charger to charge the carbon nanotube bundles, and the charged carbon nanotube bundles are vertically attached onto a surface of an electrode, using electrophoresis.

A method of vertically aligning carbon nanotubes, the method comprising:
- growing carbon nanotubes on a substrate on which a catalyst metallic layer is formed;
- separating the grown carbon nanotubes from the substrate in a bundle shape;
- putting the separated carbon nanotube bundles in an electrolyte having a charger and mixing the carbon nanotube bundles with the charger to charge the carbon nanotube bundles;
- and
- vertically attaching the charged carbon nanotube bundles onto a first electrode in the electrolyte by using electrophoresis.
