Method and device for the production of carbon nanotubes

摘要

Carbon nanotubes are produced by successively repositioning an axially extending rod-like carbonaceous anode (6) relative to a cathode surface (2a) such that a tip end surface of the anode (6a) successively faces on different portions of the cathode surface while impressing a direct current voltage therebetween, so that an arc discharge occurs with the simultaneous formation of carbonaceous deposits containing carbon nanotubes on each of the portions of the cathode surface. The carbonaceous deposits are scraped and collected. A device for carrying out the above method includes a driving member (5) for displacing the cathode surface relative to the anode.
