TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The single platelets is less than about 200microns long, and less than 0.1 microns thick. The composite material contains graphite (less than or equal to50 vol %). The graphite platelets are present to make the composite material conductive. The polymer is a thermoplastic or thermoset polymer. A graphite precursor contains a chemical that was vaporized in part(s) by heat to form the expanded graphite. The polymer is epoxy resin, polyamides, proteins, polyesters, polyethers, polyurethanes, polysiloxanes, phenol-formaldehydes, urea-formaldehydes, melamine-formaldehydes, celluloses, polysulfides, polyacetals, polyethylene oxides, polycaprolactams, polycaprolactons, polylactides, polyimides, or polyolefins. The composite material contains expanded graphite (less than 8 wt.%). The chemical agent is inorganic oxy acid. The expanded graphite is grafted with acryl amide. Preferred Methods: The expanded graphite has been formed in a radio frequency wave applicator by heating a graphite precursor with the radio frequency waves. The polymer and expanded graphite have been heated together with a radio frequency wave applicator. A precursor graphite has been treated with a fuming oxy acid and heated to form the expanded graphite. The expanding is by microwave or radio frequency heating.
