Single-walled carbon nanotube / polypyrrole thermoelectric composite materials

A single-walled carbon nanotube/polypyrene (SWCNT/PPy) thermoelectric composites were prepared by an in situ oxidative polymerization method. The effect of SWCNT composition on the microstructure of the SWCNT/PPy nanocomposites was investigated. The thermoelectric properties of the composites were measured at different temperatures between 298 K and 398 K. Both of the electrical conductivity and the See beck coefficient of the SWCNT/PPy nanocomposites with 40% SWCNT loading increased simultaneously in the measured temperature. A maximum power factor of 5.46 μWm -1 K -2 was obtained at 398 K for the SWCNT/PPy nanocomposite with 40 wt% SWCNT loading.
