 · For natural graphite, planetary ball mill is an effective method for the cleavage of the graphite sheets. However, the graphite sheets with crinkles of EG will be adhered together during the impact of the steel balls, forming flexible graphite foils with superior anti-stripping performance [18] , [19] , as shown in Fig. 6 .

Nanostructure Evolution Evolution of Expanded Graphite …

Expanded graphite (EG) was ball-milled in a high-energy mill (planetary-type) under an air atmosphere and subsequently annealed under a vacuum atmosphere. The products were characterized by X-ray diffraction (XRD). The results show that the ball-milling ...
