Functionalized graphene (G-MA) was prepared by a facile wet ball milling strategy, which achieved exfoliation and functionalization of graphite simultaneously. The G-MA showed excellent dispersion in water and polar solvents. Thus, a G-MA coating was prepared from G-MA in mixed solvents (H 2 O–ethanol) without binder or surfactant.

Ball milling was selected because it is a well-established indus-trial grinding technique and can be scaled up easily.[11] During grinding, large ZrO 2 balls fragment large graphite particles into small ones through high-speed crash, while small ZrO 2 balls detach small graphite particles into many thin graphene sheets through shear (Figure2 ...
