PRODUCTION OF NANOTUBES

摘要

Apparatus for production of carbon nanotubes comprises a vacuum chamber, electrodes and a power supply to form an arc between the electrodes together with a conduit that extends into the vacuum chamber from the outside and enables graphite powder to be introduced directly into the arc formed between the electrodes. A feeder is provided to feed an anode into the chamber. In one embodiment, the electrodes include a plurality of anodes arranged in an array. The cathode is arranged to be rotatable with a trimmer to remove debris from the cathode surface. Methods of production of nanotubes using the apparatus are also provided.
