Abstract
A method and apparatus comprising expanded, or flexible, graphite mixed into a polymer material is disclosed. A method for using expanded graphite that has been pre-compressed prior to milling to enable a polymer material to accept an electrostatic modification to the surface or to dissipate electrostatic discharges. Other embodiments relate to methods of making polymer materials, methods of making molded polymer articles or objects, and methods of electrostatically modifying molded conductive polymer materials.
