Abstract: Bi0.5Sb1.5Te3/polyaniline composites were prepared by mechanical blending and in-situ polymerization, and their transport properties were measured. It was found that for the composites with 1%, 3%, 5% and 7% polyaniline (mass fraction) respectively, which were prepared by mechanical blending, the power factors decrease by about 30%,50%,55%and 65% compared with the Bi0.5Sb1.5Te3 samples, which is mainly due to the remarkable decreases of the electrical conductivity. The electrical conductivity and power factor of the composites samples with 7% polyaniline prepared by in-situ polymerization are higher by about 65%and 60%,respectively, than that of the corresponding samples prepared by mechanical blending.
