Recently, organic thermoelectric (TE) materials have attracted increasing attention in green energy conversion. However, researches on polymer nanostructured TE materials are still scarce, especially for the 1 D nanostructured polymer materials. In this work, 1D poly(3,4-ethylenedioxythiophene) (PEDOT) nanofiber was synthesized by a self-assembled micellar soft-template approach using anionic surfactant sodium dodecyl sulfate (SDS). Then, a flexible and free-standing PEDOT nanofiber film was prepared through a simple vacuum-assisted filtration method. FE-SEM and TEM characteristics real 1D configuration for all the PEDOT nanostructures. Through adjusting the molar ratio of SDS, oxidizing agent FeCl₃ and EDOT monomer (n_SDS: n_FeCl3: n_EDOT), nanofiber with different diameter (10–200 nm) and microtopography can be obtained. Electrical conductivity and Seebeck coefficient measurement indicates that the TE properties of PEDOT can be effectively tuned by adjusting its nanostructure, and a variation range as high as three orders of magnitude for the power factors (10^-2–10¹ μW/mK²) can be realized. Due to a more ordered structure caused by the edge-on packing mode of PEDOT chain, the sample prepared with n_SDS: n_FeCl3: n_EDOT = 30:15:7 shows the highest power factor of 7.2 μW/mK². This value can be further enhanced to 14.4 μW/mK² by constructing PEDOT nanofiber/SWCNTs composite.

最近，有机热电（TE）材料在绿色能源转换中引起了越来越多的关注。然而，对聚合物纳米结构TE材料的研究仍然很少，特别是对于一维纳米结构聚合物材料。在这项工作中，使用阴离子表面活性剂十二烷基硫酸钠（SDS）通过自组装胶束软模板方法合成了一维聚（3,4-亚乙二氧基噻吩）（PEDOT）纳米纤维。然后，通过简单的真空辅助过滤方法制备了柔性的自立式PEDOT纳米纤维薄膜。所有PEDOT纳米结构的FE-SEM和TEM特性均为真实的一维结构。通过调节SDS，氧化剂FeCl ₃和EDOT单体的摩尔比（n _SDS：n _FeCl3：n _EDOT），可以获得具有不同直径（10-200 nm）的纳米纤维和微观形貌。电导率和塞贝克系数测量表明PEDOT的TE特性可以通过电子邮件FF ectively通过调整其纳米结构调谐，以及变化范围高达三个数量级的功率因数（10 ^-2 -10 ¹ μW/ mK的²）罐被实现。由于PEDOT链的边缘堆积模式导致结构更加有序，因此以n _SDS：n _FeCl3：n _EDOT = 30：15：7制备的样品显示出7.2μW/ mK ²的最高功率因数。该值可以进一步提高到14.4μW/ mK ² 通过构建PEDOT纳米纤维/ SWCNTs复合材料。
