中文摘要：

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（ZT〉1）,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.

英文摘要：

Thermoelectric（TE） material, as one of new energy materials, is regarded as one of the most important energy-saving materials, which can directly achieve the interconversion between heat and electricity. Presently, inorganic semi-conductors are considered to be the best thermoelectric materials. However, the development of new thermoelectric material has attracted great attention owing to the scarce resource and limited performance of inorganic thermoelectric materials. As the discovery and wide application of conducting polymers（CPs）, organic thermoelectric materials have come into the sights of people over the past 30 years. The development of CPs as a promising thermoelectric material has gained great attention over the past decades. Various CPs have been developed and investigated on thermoelectric performance such as polyacetylene（PA）, polyaniline（PANi）, polypyrrole（PPy）, polythiophene（PTh） and their derivatives since 1989. Among numerous CPs, poly（3,4-ethylenedioxythiophene）（PEDOT） shows many superior properties compared to others due to its excellent environmental stability, water solubility, easy processibility, and high electrical conductivity, which brings new strategy for studies of high performance organic thermoelectric materials. The conductive PEDOT combined with an insulating poly（styrenesulfonate）（PSS） can form a stable aqueous PEDOT：PSS with a good film-forming property and has been regarded as one of the most potential thermoelectric material. In 2008, the thermoelectric performance of PEDOT：PSS pellets were reported systematically for the first time. Although its thermoelectric figure-of-merit（ZT） was as low as 10~（-3）, it was one of the highest values for CPs at that time. Soon afterwards, the thermoelectric performance of the free-standing PEDOT：PSS film achieved a ZT value as high as 10~（-2） in 2010. During these years, great attention focused on the derivatives of PTh, polyselenophene（PSh）, PANi, and polycarbazole（PCz）. Sinc
