通过方便地构建饼状结构的新策略已被开发用于制备聚（3，4-乙撑二氧噻吩）还原的氧化石墨烯（PEDOT-rGO）纳米复合材料，其具有大大增强的热电性能。通过模板导向的原位聚合，由于强的π-π界面相互作用，PEDOT层的厚且均匀的涂层方便地生长在rGO纳米片表面的两侧上。纳米复合材料在室温下表现出显著增强的热电性能，功率因数为5.2 +/- 0.9 × 10（-6）W m（-1）K-2，是PEDOT的13.3倍。
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.
