【摘要】：热电材料能够直接实现热能与电能的相互转换,是重要的新型环保能源转换材料之一.无机半导体材料是当前性能最好的热电材料,然而由于资源、性能及价格的局限而难以实现大规模工业化应用.因此,发展新型高性能热电材料已成为当前重要研究领域.导电高分子(CPs)作为一种潜在的热电材料,其研究已有三十余年,然而在2000年之前,因其性能不佳而未引起高度关注.2008年,聚3,4-二氧乙撑噻吩(PEDOT)热电优值(ZT)首次被报道超过10~(-3),为发展高性能有机热电材料带来新的曙光.此后,大量新技术和方法应用于PEDOT热电性能的改善和提高.近十年来,PEDOT的ZT值迅速从10~(-4)提高到10~(-1),使PEDOT成为最有希望的有机热电材料之一.尽管PEDOT热电材料离实际工业化应用仍有较大差距(ZT1),但依然是未来有机热电材料中可能获得重大突破的p型有机热电材料.本文简要归纳了导电PEDOT作为热电材料的优势、发展历程、性能改善的方法及其未来发展趋势.
[Abstract]:Thermoelectric material is one of the important new environmental energy conversion materials, which can directly realize the mutual conversion of heat energy and electric energy. Inorganic semiconductors are the best thermoelectric materials at present. However, due to the limitations of resources, properties and prices, it is difficult to realize large-scale industrial applications. Therefore, the development of new high-performance thermoelectric materials has become an important research field. As a potential thermoelectric material, conductive polymer (CPS) has been studied for more than 30 years. However, before 2000, it did not attract much attention because of its poor performance. Poly (3o 4- dioxoethylenethiophene) thermoelectric value (ZT) has been reported for the first time, which brings a new dawn for the development of high performance organic thermoelectric materials. Since then, a large number of new technologies and methods have been applied to improve the thermoelectric performance of PEDOT. In the last ten years, the ZT value of PEDOT has been rapidly increased from 10 to 10, making PEDOT one of the most promising organic thermoelectric materials. Although the PEDOT thermoelectric material is still far from the actual industrial application, it is still the p-type organic thermoelectric material which may make great breakthrough in the future organic thermoelectric material. In this paper, the advantages and development of conducting PEDOT as thermoelectric materials, the methods of improving its performance and its future development trend are summarized briefly.
