Abstract
Electrically conductive compositions of carbon nparticles having thin coatings of conductive polymer are disclosed. The thin coatings of conductive polymer electrically interact with each carbon particle and protect the carbon particles from conductive failure. Because the conductive compositions of coated carbon particles maintain their conductive characteristics even after long term exposure to chemicals, they are useful as filler materials in polymer compositions utilized to fabricate chemical delivery devices.
