摘要：
The PEDOT:PSS/Bi0.5Sb1.5Te3 powder was prepared by a solution phase process and ground in liquid N-2. Then the powder was densified by hot press. The polymer composite powder was reformed to polymer bulk. The phase structure and microstructure were investigated by XRD and FESEM. The electrical transport properties and thermal conductivity were measured. The results show that 90% (mass fraction) Bi0.5Sb1.5Te3 with PEDOT:PSS specimen gets the highest ZT value of 0.1 at 75 degrees C which is 40 times higher than that of pristine PEDOT:PSS specimen. The Seebeck coefficient is greatly improved with the increase of Bi0.5Sb1.5Te3 content. The continuous distribution of inorganic phases is the key to improve Seebeck coefficient of composites.
