Upon consideration of intrinsic insulated poly(styrenesulfonate) in conductive PEDOT:PSS poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate), we investigated the structure homogeneity of PEDOT:PSS on its hole injection/extraction property in our previous work. For an enhancement of the structural homogeneity of PEDOT derivatives, conductive dispersant poly(diphenylamine-4-sulfonic acid) (PDAS) was applied to efficiently dope PEDOT to obtain a new water-dispersed conductive polymer PEDOT:PDAS. Compared with traditional PEDOT:PSS, PEDOT:PDAS showed much higher work function (5.38 eV), lower acidity (pH of about 7), outstanding film formation, and prospective structural homogeneity. It is worth mentioning that the conductivity of PEDOT:PDAS (0.135 S cm–1) was an order of magnitude higher than that of PEDOT:PSS-4083 (0.02 S cm–1) although PEDOT:PDAS exhibited very low PEDOT content. Organic solar cells using PEDOT:PDAS as the extraction layer showed comparable performance with the PEDOT:PSS control devices. More interestingly, PEDOT:PDAS powder can be redispersed several times because of the weak aggregation among PDAS backbones, and our result provides a practically feasible approach for the efficient storage and transportation of PEDOT ink for future industrial applications such as antistatic coating.

具有高功函,电导率,可逆分散性的半导电聚合物掺杂PEDOT及其在有机太阳能电池中的应用
考虑到导电PEDOT:PSS聚(3,4-乙撑二氧噻吩):聚(苯乙烯磺酸盐)中的固有绝缘聚(苯乙烯磺酸盐),我们在先前的工作中研究了PEDOT:PSS的结构均匀性对其空穴注入/萃取性能的影响。为了增强PEDOT衍生物的结构均匀性,应用导电分散剂聚二苯胺-4-磺酸(PDAS)有效地掺杂PEDOT,以获得新的水分散型导电聚合物PEDOT:PDAS。与传统的PEDOT:PSS相比,PEDOT:PDAS具有更高的功函数(5.38 eV),较低的酸度(pH约为7),出色的成膜性和预期的结构均一性。值得一提的是PEDOT:PDAS的电导率(0.135 S cm –1)比PEDOT:PSS-4083(0.02 S cm –1)高一个数量级,尽管PEDOT:PDAS的PEDOT含量非常低。使用PEDOT:PDAS作为提取层的有机太阳能电池表现出与PEDOT:PSS控制设备相当的性能。更有趣的是,由于PDAS主链之间的聚集力较弱,PEDOT:PDAS粉末可以再分散几次,我们的结果为有效存储和运输PEDOT油墨用于未来的工业应用(如抗静电涂料)提供了一种切实可行的方法。
