The synthesis of new materials containing multi-walled carbon nanotubes (MWCNTs) and the microstructure of alumina particles were investigated and characterized. The MWCNTs and alumina particles were ground under both the dry and wet conditions with various rotation speeds (200–400 r/min) in planetary ball milling machine, and their combination …

Then, in the fourth part after choosing the ball mill as a process for mixing XSBR and CNTs, the milling time is optimized. The effect of functional groups on the CNT dispersion is examined in the fifth part. The last part is devoted to the effect of various chemicals on the improvement of CNT–XSBR interactions. 2. Experimental section2.1.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
