Abstract
An easy, low-cost and effective synthesis of fluorinated graphene with tunable C/F atomic ratio (RC/F) has been realized by the reaction between dispersed graphene oxide and hydrofluoric acid. The results show that fluorine is grafted onto the basal plane of graphene, and the RC/F can be easily adjusted by controlling the reaction conditions. The as-synthesized fluorinated graphene exhibits a sheet-like morphology with 1–2 layered thickness and tunable bandgap energy from 1.82 to 2.99eV, which has potential applications in optoelectronic and photonic devices.
