The structure of nanographene and nanographite intercalates in solution

DOI

We aim use SANS to study in situ structure of solutions of uncharged and charged graphene formed by dissolving graphite and graphite intercalation compounds. We wish to compare and contrast scattering from solutions prepared by sonication graphites in deuterated THF, DMF and NMP with those formed from the graphite intercalation compounds of formula MCn:x(ND3). The latter are made up of negatively charged graphene sheets whose solubility is aided by charge-balancing counterions M = Na, K and Ca. In situ SANS is ideally suited to this work, because it is able to distinguish between single and multi-layer entities. We anticipate that solutions of uncharged graphene will contain larger agglomerates, including those formed by folding single sheets. Charged graphene sheets, on the are likely to remain as isolated plates due to inter- and intra-plate Coulombic respulsion.
