Abstract
A method of making chemically modified carbon-based materials for engineering purposes from a precursor containing graphite fluoride by using halocarbons or elemental sulfur as chemical agents that diffuse into the lamellar crystal structure of the graphite fluoride and permit defluoridation at a controlled rate upon heating, to produce fluoride-free intermediate carbon material and, upon further heating to form a graphitized, chemically modified carbon.
