Ball milling effect on the structure of single-wall carbon
Ball milling effect on the structure of single-wall carbon

Ball millingis regularly applied tocarbonmaterials. Applying graphite, it was used to produce highly curvednanostructures, , to insert lithium or to improve the hydrogen storage capacity of the material , . In this paper, we propose to use this grinding method onsingle-wall carbon nanotubes(SWNTs).

Ball‐Milling Modification of Single‐Walled Carbon

Abstract. Single‐walled carbon nanotubes(SWNTs) can be successfully cut with relatively homogeneous sizes using aplanetary mill. The optimized conditions produce highly dispersible SWNTs that can be efficiently functionalized in a variety of synthetic ways. As clearly shown by Raman spectroscopy, themilling/cutting procedure compares very...

Themillingis carried out at room temperature for up to 150 hours. Followingmilling, thepowderis 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 theball millingprocess formsnanotube nuclei, and the annealing process activatesnanotube growth.

Ester Vázquez and colleagues, Universidad de Castilla-La Mancha, Spain, report the use of a planetary retschball mill, which consisted of stainless steel balls within a grinding bowl, to cut and disperse single-wallednanotubes(SWNTs). Air, high rotational speeds, and longmillingtimes led to partial or almost total destruction of SWNTs.
