There has been an increase in interest in developing functional polymer composites based on green chemistry principles. The purpose of this study was to investigate the preparation of functional epoxy/carbon nanotube nanocomposites using ball milling methods. In contrast to mechanical mixing, ball milling promoted good dispersion of CNTs within the epoxy matrix, thereby improving their ...

The working of a ball mill can be understood as follows: A powder mix is positioned in ball mill and is subjected to high energy collision by the balls (Figure 1). The ball milling process can be summed up as: ... Additionally, by coating the grinding tools with ductile materials, the chances of contamination can be reduced further. To minimize

By comparison, in the Fig. 1b 3roll mill process, the samples are moved from the firstsecond roll to the secondthird roll. Because of the opposite spin directions of each roll, shearing forces are generated in the space between the roll and the rolls. This force allows the sample to mix, milling, and dispersion efficiently [30,31,32,33].

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
