End morphology of ball milled carbon nanotubes

Synthesis and characterization of nickel catalysts supported on different carbon materials

“…1 The TEM image of the ball-milled nanotube sample reveals two clearly visible features: the nanotube ends are open and their length is somewhat shorter due to the breaking the original nanotubes. A third characteristic feature is also observable for the ball-milled MWNTs: milling-induced surface imperfections on the outer shells could be identified in agreement with previously published results [20]. The dangling bonds at the open tube ends and at the surface vacancies are saturated by -COOH, -OH and =CO groups [21].…”

Incorporation of multi-walled carbon nanotubes into high temperature resin using dry mixing techniques

“…Ballmilling is a mechanical process that leads to local generation of high pressure as a result of the collision between the grinding media [23].…”

Chemically Modified Carbon Nanotubes: Derivatization and Their Applications

“…Konya et.al. have shortened the MWCNTs using ball milling under ambient conditions and proposed different mechanisms for the cleavage of tubes based on the morphology of broken ends [85]. They have modified the MWCNTs with thiol, amine, amide, carbonyl and chlorine in presence of specific atmosphere through milling.…”
