Organic salt-assisted liquid-phase exfoliation of graphite to produce high-quality graphene

- Certain common organic salts are first used for liquid-phase exfoliation of graphene.
- They exhibit efficient assistance for graphite exfoliation in some organic solvents.
- Up to 123 times enhanced exfoliation efficiency is achieved in DMSO.
- The organic salt-assisted exfoliation method is simple, efficient, safe and economical.
