Abstract
In one or more embodiments, the present invention is directed to an electrically conductive polymer composition comprising a conductive metal filler material comprising a plurality of metal particles and one or more carbon-based filler material substantially homogenously dispersed throughout a polymer matrix, wherein the aspect ratio of the one or more carbon-based filler material is at least ten times greater than the aspect ratio of the conductive metal filler material comprising a plurality of metal particles. In one or more embodiment, the carbon-based filler material will comprise at least one of carbon nanotubes, multi-walled carbon nanotubes and edge-functionalized graphene.
