Mar 29, 2017· First, large‐volume, high‐concentration, plane‐defect‐free, few‐layergraphenedispersion is fast produced fromgraphiteat high yield throughball milling. The exfoliatedgraphenedispersion is further processed intographenepaper through fast filtration, …
Functionalizedgraphene(G-MA) was prepared by a facile wetball millingstrategy, which achieved exfoliation and functionalization of graphite simultaneously. TheG-MAshowed 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. The scanning electron microscope (SEM) images of theG-MA…

Wetball millingwas used to exfoliate graphite platelets intographenesin a liquid medium. Multi-layeredgraphitenanosheets with a thickness of 30 to 80 nm were dispersed into N, N- dimethylformamide ( DMF) and exfoliated by shear-force-dominatedball millingcarried out in a planetary mill. After high-speed centrifugation, irregular shaped single- and few-layergraphenesheets (≤3 layers) having a thickness …
