The anionic graphite produced by salt-assisted ball milling showed different behavior than natural graphite in the LPE process. The thickness and size of graphene is usually controlled by centrifugation speed, but we found that the dispersion quality obtained from anionic graphene does not seem to be sensitive to centrifugation.
