| Research Abstract |
Hybridization of electroconducting polyaniline with bismuth telluride nanoparticles improved the thermoelectric performance of polyaniline by one order of magnitude. Dispersion of Pt or Au nanoparticles, which are environmentally more friendly than bismuth telluride ones, into polyaniline or PEDOT/PSS enhanced the electrical conductivity of the conducting polymers as well. It was first reported that the dispersion of enough small Au nanoparticles into PEDOT/PSS increased not only electrical conductivity but also Seebeck coefficient. We also succeeded in the preparation of n-type thermoelectric materials composed of polymer complexes although the performance was still low.
