Ball Milling Process Carbon Nanotubes

Ball milling of graphite and muilti wall carbon nanotubes . The ballmilling of mwcnts under impact mode usually resulted in the formation of an amorphous phase, whereas that under friction mode induced the fattening of nanotubes the results showed that a variety of carbon nanomaterials could be obtained by the proper controlling of ball milling.

Production Methods For Carbon Nanotubes Including Arc

May 17, 2006 The milling is carried out at room temperature for up to 150 hours. Following milling, the powder is annealed under an inert gas flow at temperatures of 1400 C for six hours. The mechanism of this process is not known, but it is thought that the ball milling process forms nanotube nuclei, and the annealing process activates nanotube growth.
