Dear Faisal Nazeer,

Please have a look on following papers:

Solvent-Exfoliated Graphene at Extremely High Concentration

Article Solvent-Exfoliated Graphene at Extremely High Concentration

Using ethanol, ether or acetone could be a great idea.

Best,

Dear Faisal Nazeer,

As you are looking for a solvent to disperse graphene make use of N,N-dimethylformamide, N-methyl-2-pyrrolidone, tetrahydrofuran, ethanol, and ethylene glycol that would be suitable.

With Best Wishes,
