They used ballmilling with melamine 2,4,6triamine1,3,5triazine to exfoliate graphite through mutual interactions under solid conditionshe strong adsorption of melamine, an aminotriazine, on graphite creates 2d molecular assemblies on graphite, which weaken the van der waals forces between graphite layers and results in exfoliation.
