二甲基亚砜改性聚(3,4-乙撑二氧噻吩):聚苯乙烯磺酸薄膜的研究及应用进展

二甲基亚砜(DMSO)被称为“万能溶剂”,除了在化学、医学、化妆品等领域的常规应用,在有机电子领域也有展现出特色应用。 聚(3,4-乙撑二氧噻吩):聚苯乙烯磺酸(PEDOT:PSS)是一类卓越的水分散性导电聚合物材料,具有优异的可加工性、混合性、生物兼容性、成膜性以及可商业规模生产等优势,被广泛应用于抗静电涂层、透明电极、有机太阳能电池、超级电容、生物传感等新材料和绿色能源领域。 DMSO对调控PEDOT:PSS薄膜的形貌、导电、热电、功函,界面接触、力学、自修复等性能具有重要作用。 基于我们团队及国内外学者在本领域的研究成果,本文系统综述了DMSO对PEDOT及其衍生物:PSS(PEDOTs:PSS)作用的效果及其机制,探讨了应用中面临的问题与挑战。

Research and Application Progress on Dimethyl Sulfoxide Modified Poly(3,4-ethylenedioxythiophene): Poly(styrenesulfonic acid) Films

Dimethyl sulfoxide (DMSO), known as a “universal solvent”, is not only used routinely in chemistry, medicine, cosmetics and other fields, but also has its own applications in the field of organic electronics. Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS), as a conductive polymer materials with excellent water dispersion, has the advantages of excellent machinability, miscibility, biological compatibility, film-forming property and commercial scale production, and is widely used in antistatic coating, organic solar cells, biological sensors, and other areas of the new materials and green energy. DMSO plays an important role in regulating the properties of PEDOT:PSS films, such as morphology, conductivity, thermoelectricity, power function, interface contact, mechanics, and self-healing. Based on the research results of our team, other domestic and foreign scholars in this field, this paper systematically reviewed the effect and mechanism of DMSO on PEDOT and its derivative:PSS (PEDOTs:PSS), and discussed the problems and challenges in the application.
