Facile Fabrication and Thermoelectric Properties of PbTe-Modified Poly(3,4-ethylenedioxythiophene) Nanotubes

摘要

In this paper, we presented a facile route to poly(3,4-ethylenedioxythiophene) (PEDOT) and PbTe-mod-ified PEDOT nanotubes. The nanotubes were prepared by an in situ interfacial polymerization method. The phase structure and morphology of the powders were characterized by X-ray powder diffraction, infrared spectroscopy, and transmission electron microscopy, respectively. The thermoelectric properties of the powders after being cold pressed were measured at room temperature. The materials exhibit extremely large See-beck coefficient values, which is promising for thermoelectric applications.
