Abstract

Global warming and environmental pollution from fossil fuels have spurred the need for clean energy technologies, among which thermoelectric (TE) devices are promising due to their ability to convert waste heat into electricity. Conducting polymers, particularly poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS), have emerged as notable organic TE materials owing to their inherent low thermal conductivity, non-toxicity, and mechanical flexibility. PEDOT:PSS exhibits good stability under high doping level, yielding high electrical conductivity over 1000 S cm⁻¹. This review focuses on the enhancement of the TE performance of PEDOT:PSS through strategies such as post-solvent treatments to selectively remove excess PSS, thereby improving charge carrier mobility and electrical conductivity. Additionally, modifying the interaction between PEDOT and PSS can optimize the macro- and microstructure, leading to improved charge transport properties. The formation of PEDOT:PSS nanocomposites further enhances the Seebeck coefficient and electrical conductivity by enabling effective energy-filtering and improved charge transport pathways. These advancements underscore the potential of PEDOT:PSS in developing efficient, flexible, and stable TE generators for various applications.

基于 PEDOT:PSS 的高性能热电技术

化石燃料造成的全球变暖和环境污染激发了人们对清洁能源技术的需求，其中热电（TE）设备由于能够将废热转化为电能而大有可为。导电聚合物，尤其是聚(3,4-亚乙二氧基噻吩):聚苯乙烯磺酸盐（PEDOT:PSS），因其固有的低热导率、无毒性和机械柔韧性，已成为引人注目的有机热电半导体材料。PEDOT:PSS 在高掺杂水平下表现出良好的稳定性，可产生超过 1000 S cm-1 的高导电率。本综述重点介绍通过后溶剂处理等策略提高 PEDOT:PSS 的 TE 性能，以选择性地去除过量的 PSS，从而提高电荷载流子迁移率和导电性。此外，改变 PEDOT 和 PSS 之间的相互作用可优化宏观和微观结构，从而改善电荷传输性能。PEDOT:PSS 纳米复合材料的形成通过实现有效的能量过滤和改善电荷传输路径，进一步提高了塞贝克系数和导电性。这些进展凸显了 PEDOT:PSS 在为各种应用开发高效、灵活和稳定的 TE 发生器方面的潜力。图表摘要提高 PEDOT:PSS 热电性能的策略
