ball milling graphene

Functionalizedgraphene(G-MA) was prepared by a facile wetball millingstrategy, which achieved exfoliation and functionalization ofgraphitesimultaneously. TheG-MAshowed excellent dispersion in water and polar solvents. Thus, aG-MAcoating was prepared from G-MA in mixed solvents (H 2 O–ethanol) without binder or surfactant. The scanning electron microscope (SEM) images of theG-MA…
