Abstract
A method of making expanded graphite. The method comprises grinding flexible graphite foil, preferably recycled material, to a small particle size, wetting the graphite foil with a water solution, thermally shocking the particles to expand them, mixing the expanded graphite with a thermoset phenolic resin, heating the mixture under pressure to form a solid sheet and then heat treating the solid sheet.
