    Abstract: A blended thermoplastic composition includes: from about 20 wt % to about 99 wt % of a thermoplastic polymer element; from about 1 wt % to about 60 wt % of a graphite-based filler element including at least about 0.01 wt % functional groups on a surface of the graphite-based filler element; from about 0.1 wt % to about 30 wt % of a functional agent element; and from about 0 to about 50 wt % of a thermally conductive and electrically insulative filler. The functional agent element includes functional groups that interact with the functional groups on the surface of the graphite-based filler element, resulting in an increase of the volume resistivity of the blended thermoplastic composition that is at least 1*102 greater than the volume resistivity of a substantially identical electrically conductive blended thermoplastic composition that does not include a functional agent element.
