    Abstract

    Polythiophene films were synthesized by electrolytic polymerization using nitrobenzene as a solvent and tetra-n-butylammonium as an electrolyte. The electrolytic concentration and thiophene concentration were synthetic parameters. We have 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. High electrical conductivity was achieved by both high carrier concentration and high Hall mobility, which are due to high compactness of polymer structure.
