Abstract
Reduced graphene oxide/bismuth telluride (rGO/Bi<sub>2</sub>Te<sub>3</sub>) bulk composite materials containing the poreforming agent, sodium chloride (NaCl), were prepared by a hot-pressing sintering method after mixing rGO/Bi<sub>2</sub>Te<sub>3</sub> nanopowders with NaCl powders. Three-dimensional connected holes formed in the bulk composite materials after removing the NaCl pore-forming agent. Next, rGO/Bi<sub>2</sub>Te<sub>3</sub>/poly(3,4-ethylen edioxythiophene):poly(styrene sulfonate (PEDOT:PSS) nanocomposite bulk materials were prepared by filling PEDOT:PSS into the as-prepared three-dimensional connected holes in the rGO/Bi<sub>2</sub>Te<sub>3</sub> bulk composite skeletons. The effects of the PEDOT:PSS filling procedure on the compositions and microstructures of the rGO/Bi<sub>2</sub>Te<sub>3</sub>/PEDOT:PSS nanocomposite bulk materials were studied. The influence of the contents of NaCl and measurement temperatures on the thermal electrical properties of the bulk composite materials was investigated. A power factor of 560 μW/(m<sup>-1</sup>·K<sup>-2</sup>) was obtained at 400 K for the rGO/Bi<sub>2</sub>Te<sub>3</sub>/PEDOT:PSS nanocomposite bulk materials.
