Abstract

Fluorinated graphitic materials are widely studied for various applications including energy storage, lubricants, hydrophobic coatings, neutron reflectors, etc. Here, we investigate the F₂ gas fluorination of three starting graphitic materials with different thicknesses: graphite, multi-layer graphene, and “graphene paper”. All synthesized products exhibit similar interplanar spacings, FTIR and XPS spectral characteristics, and similar compositions corresponding to graphite monofluoride CF_1.12. However, the thickness of the starting compound affects the temperature required for the fluorination and the decomposition temperatures of the resulting fluorides. Fluorinated graphite CF_1.12 prepared from graphite is stable up to 600 °C, while the stability drops dramatically for the fluorinated multi-layer graphene, which starts decomposing already at 100 °C. Besides, few-layer CF_1.12 forms stable colloidal dispersions in organic media, unlike its thicker counterpart. The obtained results will facilitate structural engineering of fluorinated nanographite materials to optimize their properties for potential applications.
