Some new synthetic approaches to graphite–fluorine chemistry

New methods for synthesising poly(carbon monofluoride)(CFx)n and tetracarbon monofluoride C4F are reported. Pyrolytic graphite has been fluorinated and a new compound, graphite oxyfluoride, has been prepared. Poly(carbon monofluoride) has been prepared in a flow reactor, in a fluidized-bed reactor, and in a high-pressure bomb reactor and tetracarbon monofluoride has been prepared by a high-pressure bomb technique. Some new structural data are presented for poly(carbon monofluoride). Recently, poly(carbon monofluoride) has been found to have a high potential as a solid lubricant and as a cathode material in high-energy batteries.
