Both kinds of solubility: An amphiphilic reduced graphene oxide (rGO) composite is synthesized by using a novel coil-rod-coil conjugated triblock copolymer as the π–π binding stabilizer. Such a graphene-based composite can be dissolved not only in organic solvents with low polarity (such as toluene and chloroform) but also in water-miscible solvents with high polarity (for example methanol).
