  Poly(3,4-ethylenedioxythiophene)/copper (PEDOT/Cu) composites were prepared by an in situ redox reaction of 3,4-ethylenedioxythiophene (EDOT) and copper(II) chloride. During the reaction, EDOT was oxidatively polymerized by Cu(II) chloride, while the Cu(II) ions were reduced to produce Cu metal particles. PEDOT/Cu composite films were also successfully prepared on CuCl2-coated poly(ethylene terephthalate) (PET) films by the vapor phase polymerization of EDOT. PEDOT/Cu films were characterized using UV–vis spectroscopy, scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) to confirm the formation of PEDOT, and the presence of metallic Cu particles.

  Poly(3,4-ethylenedioxythiophene) (PEDOT) films were synthesized by electropolymerization under an applied magnetic field on ITO glass. The effects of the magnetic field on the electrochemical polymerization of EDOT and the redox behavior were examined. The cyclic voltammetry (CV) result indicated that the applied magnetic field exceedingly accelerated the polymerization rate. The effect of the conformation of the PEDOT chains under applied magnetic field was studied by Raman spectroscopy. Scanning electron microscopy (SEM) showed the morphological changes of PEDOT film in the presence of the magnetic field. The parallel applied magnetic field induced the formation of more expanded chain structure as well as sharp crystalline morphology.
