Fluorinated graphene (CFx , x ≈ 0-1.12), also known as fluorographene, is an up-rising member of the graphene family, and has a two-dimensional layer-structure. The introduction of fluorine atoms not only reduces the surface energy of graphene and widens the band gap, but also enables it to obtain many novel interface and electrical properties. Fluorinated graphene also has excellent hydrophobicity, as well as electronic, optical and mechanical properties. In addition, it has very stable chemical and physical properties with acid and alkali resistance, and high temperature resistance, which is chemically similar to Teflon. Thus, fluorinated graphene has been described by scientific researchers as the Teflon of two-dimensional materials. Due to its excellent properties, it has been received the interest of scientists in physics, chemistry, materials and other fields, and has developed rapidly in recent years.

Synthesis and Application

• Fluorinated graphene can be synthesized mainly by two strategies: fluorination methods and exfoliation methods. Fluorination methods refer to fluorination of graphene layers with the aid of fluorinating agents. Exfoliation methods refer to exfoliation of bulk graphitic materials containing fluorine atoms, such as the commercial graphite fluoride ^[1]. Fluorination methods mainly include direct gas-fluorination, plasma fluorination, hydrothermal fluorination, and photochemical/electrochemical synthesis. Exfoliation methods include sonochemical exfoliation, modified Hummer's exfoliation, and thermal exfoliation ^[2].
• Based on unique properties controlled by F/C ratios and a two-dimensional layer-structure, fluorinated graphene can be utilized for energy conversion and storage devices (such as solar cell and lithium primary batteries), bioapplications (such as magnetic resonance imaging (MRI) contrast agent), electrochemical sensors (such as electrochemical sensing of ascorbic acid and uric acid), electronic applications (such as gate dielectric material and modified layer in organic field effect transistors (FETs)), supercapacitors, anti-corrosion and self-cleaning coatings and many others.
