摘要

摘要: 热电材料可以实现热能与电能的直接转化，是一种安全环保的新型能源材料。近年来，随着可穿戴电子设备的发展，柔性热电材料成为研究人员关注的焦点。传统无机热电材料具有优异的热电性能，但由于自身固有的脆性，限制了在柔性领域的发展。聚3, 4-乙烯二氧噻吩: 聚苯乙烯磺酸盐(PEDOT: PSS)具有高电导率、低热导率和良好的柔性，在柔性热电领域具有巨大的潜力。当选择合适的无机填料与PEDOT: PSS进行复合，可以得到优异的热电性能和良好的力学性能。本文综述了PEDOT: PSS基纳米复合薄膜的最新进展，并详细介绍了提高PEDOT: PSS基纳米复合薄膜热电性能的有效方法。最后，本文总结了实现高性能PEDOT: PSS基柔性热电材料的途径及面对的挑战。

Abstract: Thermoelectric materials can realize direct conversion between heat energy and electric energy, which are safe and environmentally friendly energy materials. With the development of wearable electronic devices, flexible thermoelectric materials attract great interests in recent years. Although conventional inorganic thermoelectric materials have excellent thermoelectric properties, their developments as flexible materials are limited because of their poor brittleness. Poly(3, 4-ethyl-enedioxythiophene): polystyrenesulfonate (PEDOT: PSS) has great potential in the field of flexible thermoelectrics due to its high electrical conductivity, low thermal conductivity and good flexibility. Excellent thermoelectric and mechanical properties can be obtained when choosing appropriate in-organic fillers to mix with PEDOT: PSS. This review focuses on the recent progress of PEDOT: PSS-based flexible thermoelectric materials. We also summarize the effective approaches for improving the thermoelectric performance of PEDOT: PSS-based flexible thermoelectric materials. Finally, we highlight the approaches and challenges for achieving high-performance PEDOT: PSS-based flexible thermoelectric materials.
