摘要：

Thermoelectric hybrid materials consisting of Bi0.5Sb1.5Te3 and 1-7 wt.% polyaniline (PAn) have been prepared by mechanical blending and cold pressing. It is found that the Seebeck coefficients of the hybrid materials are about 10% lower than the Bi0.5Sb1.5Te3 sample. It is shown that the power factors of the hybrid materials decrease significantly with the increase of the polymer content due to mainly the decline of electric conductivities.
