▎ 摘　　要

A novel strategy via the convenient construction of a pie-like structure has been developed to prepare a poly(3,4-ethylenedioxythiophene)-reduced graphene oxide (PEDOT-rGO) nanocomposite with a greatly enhanced thermoelectric performance. Via a template-directed in situ polymerization, thick and uniform coatings of PEDOT layers were conveniently grown on both sides of the rGO nanosheet surfaces due to a strong pi-pi interfacial interaction. The nanocomposite exhibited a significantly enhanced thermoelectric performance at room temperature with a power factor of 5.2 +/- 0.9 x 10(-6) W m(-1) K-2, greater than 13.3 times that of the PEDOT.
