▎ 摘  要

In situ polymerization has been used to prepare polypyrrole (PPy) supported reduced graphene oxide (RGO). The prepared PPy/RGO composites were characterized by X-ray diffraction, transmission electron microscopy, scanning electron microscopy and X-ray photoelectron spectroscopy. The thermoelectric properties of the PPy/RGO composites were studied by measuring the Seebeck coefficient, electrical conductivity and power factor. The influences of the PPy/RGO composition and acids on the thermoelectric properties were also investigated. The results show that the thermoelectric properties of PPy/RGO composites prepared by in situ polymerization are better than those of PPy/RGO blends, and the thermoelectric properties increase as RGO content increases to 40% because of the increased carrier mobility. PPy/RGO composites doped with organic acids display superior thermoelectric properties to those doped with inorganic acids.
