  • Ball milling is a grinding method that grinds nanotubes into extremely fine powders. During the ball milling process the collision between the tiny rigid balls in a concealed container will generate localized high pressure. Usually ceramic flint pebbles and stainless steel are used.25 In order to further improve the quality of dispersion and
