Nov 01, 2020#0183;#32;Graphite powders were wetmilled in a planetary ball mill (MTI, SFM1) with zirconia powders at a low speed of 300 rpm for different durations (3, 10, 20, 30, 40, and 50 h) to obtain highquality graphene. The low rotary speed of wet ball milling was set to ensure the integrity of graphene . The mixed powders (2 g) and ballmilling solvents (10
