高性能导电高分子PEDOT/PSS研究进展

The Research Progress of Poly(3,4-ethylenedioxythiophene)/ Poly(styrene sulfonic acid)——One of the Most Promising and Successful Conducting Polymers

高电导率、对空气和水高度稳定、可溶液加工处理、成本低一直是导电高分子研究领域研究人员追求的目标。经过20多年的研究发现聚噻吩的衍生物聚(二氧乙撑噻吩)与聚对苯乙烯磺酸(简写PEDOT/PSS)可以在水中形成稳定的悬浮液,涂布后可以形成高性能的导电膜,电导率可达103S cm-1(掺杂适量的极性有机溶剂),且对热、光、水、空气均具有良好的稳定性,可见光透过率良好,与其它助剂一起可以实现更优良的性能,因此在众多工业领域取得了广泛研究和应用。本文将介绍PEDOT/PSS的历史、制备方法、复合材料以及在抗静电、电致变色、有机发光二极管、太阳能电池等方面的应用。

Much research efforts of industrial, academic and government researchers have been directed towards developing materials that are application stable in the conducting state, easily processable and relatively simple to produce at low cost. Poly（3,4-ethylenedioxythiophene）/Poly（styrene sulfonic acid） （PEDOT/PSS） can form a water-soluble polyelectrolyte system with good film-forming properties, high conductivity （103 S cm-1, addition with polar solvent）, high visible light transmmissivity, and excellent environmental stability towards light, heat, air etc. Additives can further improve the properties of PEDOT/PSS, making them suitable for various application purposes. This paper mainly focuses on the history, preparation, composite materials of PEDOT/PSS, and its application in antistatics, electrochromic, organic light emitting dioxide, solar cell etc.
