Abstract: | Thermoelectric materials have received much attention recently from the viewpoint of global environmental issues and effective
utilization of energy resources. Especially those effective at relatively low temperature, such as below 100°C, which are
usually abandoned without use, have become noteworthy recently. From this point of view, organic thermoelectric materials
are most attractive, because they could be prepared at low cost and applied in various locations due to their flexibility.
We have investigated the thermoelectric properties of organic conducting polymers such as polyaniline, polypyrrole, and polyphenylenevinylene,
and succeeded in increasing the thermoelectric performance by selecting dopants, stretching conducting films, etc. Recently
we have focused on new systems of organic–inorganic hybrid thermoelectric materials. Herein we present the preparation of
a novel system of hybrids of polyaniline and bismuth(III) telluride nanoparticles, starting from bismuth(III) chloride and
tetrachlorotellurium by using polyvinylpyrrolidone as a protecting reagent, as well as their thermoelectric properties. The
hybrids prepared by this particular method showed much higher thermoelectric performance than the starting organic conducting
polymer. |
