2001-2-16 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.

2013-2-12 Ball milling was found to cut nanotubes into smaller pieces, narrow their length distribution and increase their specific surface area and surface fractal dimension. Typical length reduction was from 1300 to 200 nm, specific surface area increase from 160 to 340 m 2 g −1 and surface fractal dimension increase from 2.47 to 2.70. The pore size distribution of pristine MWCNTs exhibited a mesoporous

2011-2-15 The length and functionality of the modified carbon nanotubes (CNTs) affects their solubility, changing the way in which they can be manipulated. Most CNTs have low solubility in organic solvents, yet methods for modifying CNTs have focused on wet techniques like refluxing and sonication in the presence of large amounts of strong inorganic acids or organic solvents.

2006-5-16 Ball Milling. Ball milling and subsequent annealing is a simple method for the production of CNTs. Although it is well established that mechanical attrition of this type can lead to fully nano porous microstructures, it was not until a few years ago that CNTs of carbon and boron nitride were produced from these powders by thermal annealing.
