Effect of static pressure on ultrasonic liquid phase exfoliation of few-layer graphene

“…However, the toxicity of these solvents poses safety concerns. Ionic liquids are liquid salts with surface energies comparable to graphene [9] , [10] . Although they have the potential to stabilize dispersions effectively, their preparation process is relatively complex and expensive.…”
