ball milling graphite

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…

    Effect of extended ball milling on graphite ScienceDirect

    Feb 03, 2003·Ball millingof graphite for up to 1000 h in vacuum lead to the formation of a highly reactive carbon which was found to chemisorb large amounts of carbon dioxide after exposure to air. The presence of CO 2 on the surface was confirmed by FTIR and its removal during heating was demonstrated by TG–FTIR and FTIR of heated powders. The chemisorption was incomplete even after …

    Graphite layers can be shifted by ball milling a mixture of graphite and chemically inert water-soluble inorganic salts. The ensuing water washing and sonication of the milling products can result in the production of graphene powders. There are also practical advantages to dry milling when the combined functionalization and exfoliation is required.
