Sep 16, 2013· The statistical analysis of the length distribution of catalytic chemical vapour deposition synthesized multi-walledcarbon nanotubescut by planetaryball millingis reported. The nanotube lengths follow a log-normal distribution in a broad range of grinding time and rotational speed. We show that the scale parameter of the distribution, which equals the mean of the natural logarithm of the ...

Theball-milling of MWCNTs under impact mode usually resulted in the formation of an amorphous phase,whereas that under friction mode induced the fattening of nanotubes. The results showed that a variety of carbon nanomaterials could be obtained by the proper controlling of ball milling.

Abstract We present a fast method to prepare hybrid materials ofpolyaniline (PAni) withcarbon nanotubes (CNTs, bothundoped and nitrogen-doped) by ball milling withoutsolvents or strong oxidants. PAni forms nanoparticles, attached to CNTs in a nanocomposite structure, with the nanotubes well dispersed among the polymer.

Toobtain narrow length and diameter distributions of CNTs and to open the nanotubes for improved sorption capacity for gases, ball-milling is a very useful method. However, it has also been observed that a large amount of amorphous carbon is created which clearly indicates that the tubes are damaged in different ways and that ball milling is a destructive method.

For all nanocrystalline materials prepared by high-energyball millingsynthesis route, surface and interface contamination is a major concern. In particular, mechanical attributed contamination by themillingtools (Fe or WC) as well as ambient gas (trace impurities such as O 2, N 2 in rare gases) can be problems for high-energyball milling...

During the high-energy ball milling process, the powder particles are subjected to high energetic impact. Microstructurally, the mechanical alloying process can be divided into four stages: (a) initial stage, (b) intermediate stage, (c) final stage, and (d) completion stage.
