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.

Case Study

Fluorinated Graphene for the Synthesis of Hydrophilic Modified Composites with Enhanced Anticorrosion Properties

An H, et al. Surfaces and Interfaces, 2025, 60, 106060.

A hydrophilic fluorinated graphene oxide (HFGO) was synthesized through oxidation and silane functionalization. Initially, FG was oxidized via a modified Hummers method using H₂SO₄/H₃PO₄ and KMnO₄ under controlled temperature conditions, followed by quenching with H₂O₂ and extensive washing to yield FGO. Subsequently, FGO was functionalized with (3-aminopropyl)triethoxysilane (APTES) through an ethanol-based condensation reaction at 80 °C under reflux for 8 h, producing HFGO with significantly improved dispersibility in water.

For experimental application, HFGO was incorporated into a waterborne epoxy resin (WEP) system. HFGO was first ultrasonically dispersed in deionized water and introduced into WEP under high-shear mixing, followed by the addition of curing agent and vacuum degassing. Coatings with varying HFGO loadings (0.1–0.6 wt%) were prepared on Q235 steel substrates. The optimal formulation, containing 0.3 wt% HFGO, exhibited superior anticorrosion performance, attributed to homogeneous dispersion and formation of a compact barrier film. This study demonstrates the potential of surface-modified fluorinated graphene as a high-efficiency anticorrosion additive in aqueous epoxy coatings.

Fluorinated Graphene for Artificial SEI Construction in Sodium Metal Batteries

Zhang H, et al. Chemical Engineering Science, 2026, 319, 122254.

Fluorinated graphene (FG) was applied to fabricate a robust artificial solid electrolyte interphase (ASEI) on sodium metal anodes, aiming to suppress dendrite growth and enhance cycling stability. The preparation involved drying FG at 120 °C under vacuum for 12 h, followed by its uniform deposition on freshly prepared sodium foils. Sodium blocks were cut, surface oxides removed, and then rolled into thin sheets (~12 cm²). Subsequently, 24 mg of dried FG was evenly spread on the sodium foil, yielding electrodes with an areal loading of ~2 mg cm⁻². The modified foils were punched into 10 mm discs, denoted as FG@Na. Electrochemical testing demonstrated uniform Na⁺ deposition/stripping and effective dendrite inhibition. Symmetric FG@Na||FG@Na cells achieved 1800 h stability at 0.5 mA cm⁻², while NVP||FG@Na full cells delivered superior cycling durability with 93% capacity retention over 2000 cycles at 10C.

Fluorinated Graphene for Enhancing Thermal Conductivity and Dielectric Properties in Silicone Gel Composites

Sun P, et al. Composites Communications, 2025, 53, 102162.

In this study, fluorinated graphene was employed to construct a double-oriented three-dimensional skeleton within silicone gel via an ice-template method with a dual temperature gradient. This approach enabled the in situ assembly of fluorinated graphene into a continuous network, overcoming the common challenge of filler dispersion. The experimental method ensured vertical and horizontal orientation of the skeleton, significantly facilitating phonon transport while restricting charge polarization. Finite element simulations were used to analyze the performance-enhancing mechanism of the skeleton. The resulting composites exhibited vertical and horizontal thermal conductivities of 3.34 W/(m·K) and 2.65 W/(m·K), respectively, while the dielectric constant was reduced to 80% of the neat silicone gel. This experimental strategy demonstrates the potential of fluorinated graphene skeletons in creating thermally conductive yet electrically insulating materials for advanced electronic applications.
