Figure 1.4 shows the main areas of interest for papers published on conducting (CEPs) electroactive polymers over the past 25 years, with almost half of the publications related to the synthesis of new types of CEPs or modifications to existing CEPs. The next largest area of research has been into the physics of the conduction mechanisms, while applications for CEPs accounts for fewer than 20% of publications. A further breakdown of the areas of application for CEPs sees a great deal of interest in batteries, followed by sensors, membranes and polymer light emitting diodes (PLEDs). 

Light-emitting diodes (LEDs) based on the electroluminescent conjugated polymers (Fig. 47) have attracted significant attention, both in academic research and industrial development, and are now on the edge of commercialization (Burroughs et al. 1990, Barth and Bassler 1997). Polymer LEDs require properties such as shown in Table 11. Recently, ef-...
