Feb 16, 2001· Short multi-wall carbon nanotubes can be obtained by ball milling. The average length of the ball milled carbon nanotubes, synthesised by decomposition of acetylene on different types of supported metal catalysts, is ca. 0.8 μm. The cleavage was caused by the collision between one agate ball and the nanotube powder contained in an agate mortar.
The ball milling process is a good method to obtain short (<1 μm) multi-wall carbon nanotubes with open tips. The cleavage of catalytically synthesised multi-wall carbon nanotubes (either crude or purified) gives short nanotubes.
