摘 要：Ca3Co4O9/polyaniline bulk composites have been successfully fabricated by ball-milling and hot-pressing method.Our results indicate that the Seebeck coefficient can be increased nearly by 400%with adding15 wt%Ca3Co4O9 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 50times 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.
