  • Preparation of graphene via wet ball milling and in situ

    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 (H2O–ethanol) without
