导电有机聚合物在电子学中的应用主要有两种：作为各种器件的结构材料和作为化学传感器的选择层。在任何一种情况下，与周围气体的相互作用都是至关重要的。它可能会损害基于导电聚合物的设备的性能，而它在传感器中是有益的。电导率一直是人们感兴趣的主要性质。功函数与导电性有关，但原则上是一种不同的性质，很少受到关注。我们的目的是讨论导电聚合物在这两种类型的电子应用中的可用性，根据这两个参数。
Conducting organic polymers have found two main kinds of application in electronics so far: as materials for construction of various devices and as selective layers in chemical sensors. In either case, interaction with ambient gases is critical. It may compromise the performance of a device based on conducting polymers, whereas it is beneficial in a sensor. Conductivity has been the primary property of interest. Work function-related to conductivity, but in principle a different property-has received only scant attention. Our aim here is to discuss the usability of conducting polymers in both types of electronic applications in light of these two parameters.
