Résumé
Fluorinated nanocarbons are of great interest for high power and energy densities of primary lithium batteries and as high-temperature solid lubricants. The maintenance of the nano-objects through solid—gas fluorination is not obvious and dedicated fluorination ways should be performed for such purpose. New fluorination ways have been conducted by the F2 team of the Institute of Chemistry of Clermont-Ferrand from Clermont University in order to covalently graft fluorine atoms onto carbons without degradation of the carbon texture into volatile carbon fluorides such as CF4.
The various curvatures of 0D (fullerenes, nanodiamonds, nanographitized carbon blacks), 1D (nanotubes), and 2D (graphene, nanodisks) nanocarbons allow to modulate the C−F bond strength. This bond strength must be deeply characterized in order to master the consecutive properties. Among the numerous available characterization ways, solid-state NMR is of prime interest. Each fluorinated nanocarbon family will be detailed owing to its synthesis way, its C−F bond, and the known properties.
