摘　　要：热电材料是一种可以直接将热能转化为电能的功能材料,基于热电材料的能源技术属于清洁能源技术。由于无机热电材料存在毒性大、脆性大、成本高等局限性,有机热电材料引起了人们的广泛关注。有机热电材料中,聚(3,4-乙烯二氧噻吩):聚苯乙烯磺酸盐(PEDOT:PSS)凭借高导电、低导热等特性成为研究热点,但其综合性能仍未满足应用需求,因此研究者采用多种方法对PEDOT:PSS进行改性以提升其热电性能。本文主要介绍了利用离子液体、无机填料、碳纳米管和小分子试剂等与PEDOT:PSS共混改性以提升其热电性能的研究进展,最后总结了进一步提高PEDOT:PSS热电性能所面临的问题与未来的研究方向。Thermoelectric material is a kind of functional materialthat can directly convert thermal energy into electrical energy.The energy technology based on thermoelectric material is a kind of clean energy technology.Due to the limitation of inorganic thermoelectric materials,namely toxicity,brittleness and high cost,organic thermoelectric materials have aroused widespread concern.Among them,poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate)(PEDOT:PSS)has attracted lots of attention,for its high electrical conductivity and low thermal conductivity.However,its thermoelectric properties have not yet met the requirement for real applications.Thus,researchers have applied various methods to modify PEDOT:PSS to improve its thermoelectric performances.This paper mainly introduces the research progress of the modification of PEDOT:PSS with ionic liquids,inorganic fillers,carbon nano-materials and small molecular agents,with an aim to improve its thermoelectric properties.Potential research directions for PEDOT:PSS are also proposed.
