| 摘要 |
An electrolytic technique for exfoliation of graphite is disclosed. The electrolytic technique utilises a graphite electrode formed from aligned graphite particles in a binder such as carbonised mesophase pitch or phenolic resin. The graphite layers are aligned within 20° of an electrode surface. The electrolyte may be an ionic liquid such as an aqueous solution of poly(sodium 4-styrenesulfonate), or an acid such as sulphuric acid. Aslo disclosed are intercalated graphite particles which comprise a gradation of expansion. |
