Ball‐Milling Modification of Single‐Walled Carbon
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...

Synthesis of Nanomaterials by High Energy Ball Milling

Besides materials synthesis,high-energy ball millingis a way of modifying the conditions in which chemical reactions usually take place either by changing the reactivity of as-milled solids (mechanical activation — increasing reaction rates, lowering reaction temperature of the ground powders)—or by inducing chemical reactions duringmilling(mechanochemistry).

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.
