Abstract
Electrically conductive polymeric compositions suitable for fabricating devices for safely transporting volatile chemicals and fuels are disclosed. The electrically conductive polymeric compositions include at least one matrix polymer and an electrically conductive filler material incorporated in the matrix polymer in an amount sufficient to provide the conductive polymeric composition with an electrical conductivity of at least 10.sup.-10 S/cm. The electrically conductive filler material is intrinsically conductive polymer coated carbon black particles. The coating of intrinsically electrically conductive polymer provides a protective shield against loss of particle conductivity, contributes to the overall conductivity of the filler material and enhances the mechanical properties of the filled matrix polymer.
