Method of preparing vertically-aligned carbon nanotube under atmospheric and cold-wall heating treatments and making the same

摘要

A carbon nanotube is prepared under a non-vacuum environment. An atmospheric pressure chemical vapor deposition (APCVD) is processed with an external high frequency source and a perpendicularly-supplied gas material source for a cold-wall heating treatment. The carbon nanotube is thus obtained with a vertically aligned arrangement at a high speed and a pure quality for production.
