Abstract
A Janus graphene nanosheet (JGN) surfactant formed from a two-dimensional graphene oxide sheet and functionalized to produce an amphiphilic graphene nanosheet. The JGN may be a component of a nanofluid utilized in nanofluid flooding for oil recovery. The JGN may also be used as solid surfactants to form emulsions for oil recovery.
