Analysis of conductivity and dielectric permittivity as functions of applied AC frequency and features responsible for the giant tenso‐resistance effect in polyisoprene‐extraconductive carbon black nanoparticles composites are presently reported. The experimentally obtained results are in good agreement with the mechanism of inter‐cluster polarisation. Some deviation from the statistical percolation theory at carbon concentrations above the percolation threshold is discussed.
