Schematic view of CNT growth on catalyst particles during CVD. First, small secondary catalyst particles of the size of a CNT diameter develop, on which the nanotubes start growing. The catalyst particle is either at the top or at the bottom of the emerging nanotube.
method consists of two steps: CNTs pre-dispersion by ball-milling and the ultrasonic melt processing. Mechanical ball- milling effectively pre-dispersed CNTs on Zn ﬂakes with suitable rotational speed and ball-milling time.
It is a ball milling process where a powder mixture placed in the ball mill is subjected to high-energy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960.

We fabricated and investigated a 304 stainless steel and carbon nanotube (304SS-CNT) composite with an aim to study its microstructures and high-temperature tensile properties. 304SS powders were mixed with carbon nanotubes using ball milling and consolidated using …
Finally, the ball milling process was executed on nanocomposite powders by planetary ball mill for 2 and 4 h to make the Al (45) -1.5wt.%CNT products. The other ball milling parameters like a ball to powder ratio (BPR = 10), diameter of stainless steel balls (D = 10 mm) and rotation speed (ω = 200 rpm) were employed in medium energy level to ...
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.

This Letter proposes a novel chemo-mechanical method to in situ functionalize carbon nanotubes (CNTs). Ball milling in the presence of ammonium bicarbonate allowed the introduction of amine and amide groups onto the surface of CNTs, resulting in the conversion of the semiconducting behavior of CNTs from p-type to n-type.
