Abstract

We report a simple method that can dissolve graphene oxide (GO) in pure organic solvents (e.g., propylene carbonate) as readily as in pure water to form stable dispersions of single layer GO sheets. The GO sheets dispersed in propylene carbonate exhibited much better structural stability than those in water.
