This patent from Compagnie Plastic Omnium teaches an electrically conductive PTFE tape with improved electrical conductivity properties based on carbon nanotubes. Claim 1 reads:

1. A fluoropolymer tape having two sides,

at least one of the sides being an electrically conductive extrusion of a blended mixture, the blended mixture comprising dispersible carbon selected from the group consisting of vapor-grown carbon fibers (VGCF), and combinations of VGCF and carbon nanotubes and polytetrafluoropolymer;

wherein the sides comprise extrusions of different blended mixtures and wherein one side of the tape is more electrically conductive than the other side of the tape.
