METHOD TO PRODUCE FLUORIDATED CARBON MATERIAL Russian patent published in 2012 - IPC H01M4/58 B82B3/00 

FIELD: electricity.

SUBSTANCE: method to produce a fluoridated carbon material (FCM) includes thermal treatment of a carbon material with a reaction gas, containing fluorine and (5÷2) vol. % of fluoric hydrogen, taken at the ratio with inert gas (2÷20)-(80÷98) vol.% accordingly, and treatment is carried out under pressure of 20÷100 kPa, at the same time the carbon material is fullerene C₆₀, treatment is carried out at the temperature of 240°C for 7 hours, and the produced fluoridated carbon represents a mixture of polyfluorofullerenes, and has a chemical composition C₆₀F_n, where n is equal to 18, 36, 44, 48. The carbon material may be a mixture of fullerenes C₆₀ and C₇₀, containing 10% of fullerene C₇₀, fluoridation is carried out at the temperature of 245°C for 10 hours, the produced fluoridated carbon represents a mixture of polyfluorofullerenes C₆₀F_n, where n is equal to 18, 36, 44, and C₇₀F_n, where n is equal to 46, 52. The carbon material may be fullerene soot saturated with fullerenes C₆₀, C₇₀, the total content of which makes 5-15%, treatment is carried out at the temperature of 230÷350°C for 7-15 hours, and the produced fluoridated carbon represents a mixture of fluoridated soot with the composition (CF_0.95)n and polyfluorofullerenes C₆₀P_18÷44 and C₇₀F_46-52.

EFFECT: production of high-technology fluoridated nanocarbon materials.
