Résumé
A new and simple method of synthesizing fluorinated carbon at the gram scale is presented by reacting afluorinated alcohol with sodium at elevated temperatures in a sealed Teflon reactor. The resulting carbonnanoparticles are around 100 nm in diameter, and display a hollow shell morphology, with a significantamount of fluorine doped into the carbon. The nanoparticles disperse easily in ethanol, and are thermallystable up to 400 °C and 450 °C under air and nitrogen, respectively. The nanoparticle dispersion wasprinted onto various substrates (paper, cloth, silicon), inducing superhydrophobicity.
