Abstract
An electrically conductive filler comprises particles having a base substrate and a conductive coating. In some embodiments, the base substrate is a metal, plastic, glass, natural or synthetic graphite, carbon, ceramics, fiber or fabric. In some embodiments, the coating provides improved electrical conductivity, and the coated particle has lower electrical resistance than the uncoated base particle. Other embodiments and methods of making and using the electrically conductive filler are also disclosed.
Claims12
A composition comprising:
