| Abstract: | Conducting polythiophene films electrochemically polymerized in aqueous perchloric solu-tion have been characterized by means of reflecting FT-IR spectra, UV-Vis spectra andXPS spectra. The XPS spectra with etching technique were used to obtain the informationin depth. Water seems to participate in the polymerization process of thiopheene and intro-duce oxygen atom into the PTh structure as carbonyl group. ClO_4~- content varied withthe depth of the film. No ClO_4~- was found in the bulk, but at the surface it gave a concen-tration of 8-10mol%, lower than the concentration of PTh in organic solvents. C-Clbonds were formed during the oligomerization of thiophene in concentrated HClO_4 solutionand uniformlly distributed in the PTh film. The conductivity of PTh film is about1S/cm |
