The success of the future concept of green society relies on accelerated progress in reversing human impacts on the ecosystem. Thus, the pursuit of meeting the increasing energy needs of humanity through alternative benign means has stimulated a rapid technological evolution, which requires harnessing the dissipated waste heat. Therefore, this review presents an overview of the thermoelectric (TE) properties and applications of poly(3,4-ethylenedioxythiophene) (PEDOT):polystyrene sulfonate (PSS)/carbon composites. The carbon allotropes considered herein vary across different length scales. Therefore, this review discusses the TE behavior of the composites of PEDOT:PSS and zero-, one-, two-, and three-dimensional carbon materials. The fabrication techniques for promoting dual electronic and ionic transport in PEDOT and the ion-exchange effect for carrier tuning have also been discussed. In summary, we have discussed the TE applications of PEDOT:PSS/carbon composites and their future perspectives for TE devices.

未来绿色社会概念的成功取决于在扭转人类对生态系统影响方面的加速进展。因此，通过替代良性手段满足人类日益增长的能源需求的追求刺激了技术的快速发展，这需要利用散发的废热。因此，本综述概述了聚（3,4-乙撑二氧噻吩）（PEDOT）：聚苯乙烯磺酸盐（PSS）/碳复合材料的热电（TE）特性和应用。本文考虑的碳同素异形体在不同的长度尺度上有所不同。因此，本综述讨论了 PEDOT:PSS 和零维、一维、二维和三维碳材料复合材料的 TE 行为。还讨论了促进 PEDOT 中双电子和离子传输的制造技术以及载流子调谐的离子交换效应。总之，我们已经讨论了 PEDOT:PSS/碳复合材料的 TE 应用及其对 TE 设备的未来前景。
