New conducting copolymer nanocomposites were synthesized by the copolymerization of aniline with 3,4‐ethylenedioxythiophene (EDOT) via in situ deposition with known amount of EDOT and different aniline concentrations dispersed in aqueous medium using ammonium persulfate as an oxidizing agent. The strong interaction of poly(3,4‐ethylenedioxythiophene) (PEDOT) with polyaniline (PANI) to form PEDOT–PANI nanocomposites was supported by spectral characterization and surface morphology studies. To understand the conduction behavior of the composites, their temperature‐dependent electrical conductivity was measured in the range of 293–473 K. The conductivity of PANI was greatly increased by the copolymerization with PEDOT due to the increased delocalization of electrons and mobility of charge carriers. POLYM.
