Aqueous dispersions of TCNQ-anion-stabilized graphene sheets

Abstract

Aqueous dispersed graphene was successfully prepared via using 7,7,8,8-tetracyanoquinodimethane (TCNQ) anion as a stabilizer and expanded graphite as a starting material, which could provide a facile route to produce high quality water-soluble and organic solvent-soluble graphene sheets for various applications.
