Our results indicate that the Seebeck coefficient can be increased nearly by 400% with adding 15 wt% 0a3Co409 to the polyaniline. The thermal conductivity changes slightly with increasing filler content. The highest figure of merit, ZT can reach 5× 10-4 at 329 K for these bulk composites, which is almost 50 times larger than that of pure polyaniline, suggesting that the polymer-thermoelectric oxide composites are promising candidates for light-weight, low-cost and non-toxic thermoelectric applications.展开更多
