Freestanding poly(3,4-ethylenedioxythiophene) (PEDOT) nanowires (NWs) were synthesized using a facile, self-assembled, micellar soft-template method. Thermoelectric properties of the PEDOT NWs under different reaction conditions were measured, and optimal experimental conditions were confirmed. To obtain preferential thermoelectric performance, PEDOT NWs/graphene composite films with various graphene mass fractions were fabricated. The maximum power factor of the hybrids was observed to reach 42.0 μWm⁻¹K⁻² with 3 wt% graphene loading, corresponding to a 200% improvement compared with pure PEDOT NWs. The thermoelectric devices were investigated using the PEDOT NWs/graphene hybrids as a p-type leg and PEDOT NWs/nitrogen-doped graphene as an n-type leg. The device, in series, shows a preferable cooling effect with an approximate temperature decrease of 0.5°C after energization. Our work provides a novel means of fabricating n-type PEDOT hybrids and promotes their practical applications as thermoelectric coolers. These findings indicate a new means of developing high-performance, flexible, organic thermoelectric materials and devices.

使用简便，自组装，胶束软模板方法合成独立的聚（3,4-乙撑二氧噻吩）（PEDOT）纳米线（NWs）。测量了PEDOT NW在不同反应条件下的热电性能，并确定了最佳实验条件。为了获得优先的热电性能，制备了具有各种石墨烯质量分数的PEDOT NWs /石墨烯复合膜。观察到混合动力汽车的最大功率因数达到42.0μWm ^-1 K ^-2石墨烯负载量为3 wt％，与纯PEDOT NW相比提高了200％。使用PEDOT NWs /石墨烯杂化体作为p型支腿和PEDOT NWs /氮掺杂石墨烯作为n型支腿来研究热电器件。串联后，该装置显示出较好的冷却效果，通电后温度降低约0.5℃。我们的工作为制造n型PEDOT混合动力车提供了一种新颖的方法，并促进了其作为热电冷却器的实际应用。这些发现表明开发高性能，柔性有机热电材料和器件的新方法。
