METHOD FOR MODIFYING EXPANDED GRAPHITE AND USE OF THE MODIFIED EXPANDED GRAPHITE

摘要

The invention relates to a method for modifying expanded graphite, wherein the surface thereof is brought into contact with a plasma-activated process gas in such a way that the gas forms with the carbon atoms of the graphite stable reaction products in the form of chemical groups covalently bound to the graphite so that the chemical and physisorptive properties of the expanded graphite are modified.
