2019-12-12A monolayer of ultrathin sheets of highly hydrophobic graphene nanosheets was prepared on a large area substrate via self-assembly at the liquidliquid interface. Driven by the minimization of interfacial energy these planar shaped graphene nanosheets produce a close packed monolayer structure at the liquidliquid interface. This monolayer film shows high electrical conductivity of more ...
