Abstract :
Numerous techniques for the purification of chemically synthesized graphene have been investigated, exploiting the relative aqueous solubilities of the impurities and carbon sheets. This demonstrates that simple aqueous washing provides a reliable platform for the purification of graphene, without the need for harsh chemical treatments. The presence of cavities or pores in the as-obtained graphene structure are believed to inhibit small particles, that are interspersed throughout the material, from undergoing hydrolysis reactions.
