Graphical Abstract

Thumbnail image of graphical abstract

Fluorination of graphene yields a stoichiometric derivative of graphene with a fluorine atom attached to each carbon. Fluorographene is an optically transparent, high-quality insulator with a mechanical strength and elasticity, matching those of graphene. It is inert and thermally stable, similar to Teflon.

Abstract

A stoichiometric derivative of graphene with a fluorine atom attached to each carbon is reported. Raman, optical, structural, micromechanical, and transport studies show that the material is qualitatively different from the known graphene-based nonstoichiometric derivatives. Fluorographene is a high-quality insulator (resistivity >1012Ω) with an optical gap of 3 eV. It inherits the mechanical strength of graphene, exhibiting a Young’s modulus of 100 N m−1 and sustaining strains of 15%. Fluorographene is inert and stable up to 400 °C even in air, similar to Teflon.
