摘要
In this work, graphene is synthesized via liquid-phase exfoliation of graphite in organic solvents with addition of anthracene. Graphene concentration is enhanced by adding anthracene in organic solvents. Anthracene intercalates into the edges of graphite and results in graphene concentration enhancement. By adding anthracene in benzonitrile (BZN) solvent, the graphene concentration is increased from 0.01 to 0.03 mg/ml. The effect of anthracene in concentration enhancement is most prominent in 1-methyl-2-pyrrolidone (NMP), orthodichlorobenzene (ODCB) and BZN solvents as compared to others. With addition of anthracene, the graphene concentration in NMP and ODCB solvents is increased to 0.04 mg/ml. This facile method of concentration enhancement is highly suitable for preparing conducting graphene films and composites for various electronics device applications such as field-effect transistors, flexible paper supercapacitors.
