In this invention, the fluorinated graphene(FG) is obtained by the fluorination of electrochemically exfoliated graphene (ECG), which is found to be a one-step approach for the scalable preparation of FG. The precursor with fluorine atoms is mixed with the ECG followed by applying lower energy to produce the fluorinated graphene. This process demonstrates an eco-friend and safe as well as scalable features. We have demonstrated their multi-functional applications on surface coatings, including the outperformance anticorrosion passivation, hydrophobic surface with ultra-strong adhesion, and high safety energy storage device. This technology provided a new strategy for next-generation functional and atomic layered coatings.
