▎ 摘 要
NOVELTY - Preparing high-energy ball hammer broken wall carbon nanotube graphene comprises using the reciprocating ball hammer of the one-axis multi cylinder multidimensional ball hammer type high-energy nano ball mill for high-energy hammering, crushing the single-walled and multi walled carbon nanotubes and preparing into single-layer and few-layer graphene two-dimensional materials, where the carbon nanotube graphene has ultra-small lateral size, ultra-high specific surface area, a large proportion of sp2 bond atoms and numerous surface defects. The preparation method utilizes grinding balls made of 304, 316 stainless steel, tungsten alloy, and zirconia, and nitrogen. USE - The method is useful for preparing high-energy ball hammer broken wall carbon nanotube graphene. ADVANTAGE - The method enables to prepare high energy ball hammer wall-breaking carbon nano-tube graphene that has ultra-small transverse size, ultra-high specific surface area, more sp2 bond atom ratio and over-many surface defects. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of multi-dimensional motion of one-axis multi-cylinder ball-hammer type micro-nano high-energy ball mill.
