AbstractPolythiophene (PTh) films were prepared by the direct electropolymerization of thiophene in the ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate (BMIM)PF6. The structure and morphology of PTh films were characterized by means of the FT-IR spectrum and the scanning electron microscopy (SEM). The electrical and electrochemical properties of PTh films were examined with the UV-Vis spectrum, cyclic voltammetry (CV) and four-probe method. The results showed that when the potential for electropolymerization was controlled between +1.7 and +1.9 V (vs. Ag/AgCl), very homogeneous PTh films could be prepared in the ionic liquid (BMIM) PF6 used as solvent and electrolyte. The de-doping (reduction) and re-doping ( re-oxidation) of the PTh film prepared in ionic liquid are reversible and stable, and the conductivity of PTh films is 0.01 similar to 0.1 S/cm.
