摘要：

We have synthesized conductive polythiophene films by electrolytic polymerization using nitrobenzene as solvent and tetra-n-butyl ammonium perchrorate as electrolyte, and evaluated the thermoelectric properties of Seebeck coefficient, electrical conductivity and Hall mobility of the films in the in-plane direction. The films showed a tendency that Seebeck coefficient decreased with an increasing electrical conductivity. The figure of merit of similar to 1 x 10(-4) K-1 was achieved at the electrical conductivity of 90Scm(-1). High conductivity was due to smooth surfaces, high compactness, and high crystallinity of monoclinic structure. Electrical conductivity was strongly dependent on Hall mobility.
