The conductive polyaniline films were cast and stretched to investigate on thermoelectric properties. The thermoelectric performance of the stretched polyaniline films in the direction parallel to the stretching direction was much higher than that of the unstretched counterpart, and increased with increase of the drawing ratio. The experimental results of X-ray diffraction patterns and Vis-near IR spectra revealed that the increment is due to extended coil-like conformation and ordering of polyaniline molecules. Here we report thermoelectric properties of spin-coated conductive polyaniline films. The polyaniline films showed a tendency of increase in thermoelectric performance with decreasing in thickness of the film. Vis-near IR spectra and X-ray diffraction patterns of the films have indicated that such increment of thermoelectric performance does not originate from ordering of the molecules but are only due to extended coil-like conformation of polyaniline molecules in the film.Read More
