Novel Preparation of Poly(3,4-ethylene dioxythiophene)-Poly(styrenesulfonate)- Protected Noble Metal Nanoparticles as Organic-Inorganic Hybrid Thermoelectric Materials

抄録

Here, we describe a novel synthetic method of PEDOT-PSS (poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate))-protected Ag, Au and Pd nanoparticles(NPs) by a simple procedure, and thermoelectric properties of the PEDOT-PSS films doped with these NPs. Interestingly, PEDOT-PSS films containing small amount of PEDOT-PSS-protected Ag NPs showed a higher electrical con- ductivity than that of pure PEDOT-PSS. As a result, the PEDOT-PSS protected Ag NPs system showed a high in-plane power factor (35.2 μW m-1 K-2), which was relatively superior to that of conventional metal nanomaterial systems. Thus, we have succeeded in development of high performance organic-inorganic thermoelectric conversion films.
