Abstract
A method of making chemically modified carbon-based composite 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 a graphite fluoride-free intermediate carbon material and, upon further heating to form a chemically modified carbon that is further heated in the presence of a specified one of several chemical elements to form a composite including a coating of the specified element.
