Graphite intercalation chemistry has been known for about 160 years. Intercalation means the incorporation of ions and sometimes neutrals between graphene sheets. Looked at another way, this is chemical way a way of separating the graphene sheets in graphite. However these sheets become positively or negatively charged and remain part of an ionic assembly with intercalate ions. Recently, we've demonstrated the intercalation of very large anions between planar graphene sheets, with correspondingly large gallery dimensions. Are we on the verge of completely delaminating graphite into individual graphene sheets via this intercalation chemistry?
