“…However, by applying a correction procedure accounting for the change in reflectance of metallic electrode during the electrosynthesis (see Section 2.2.1 ), we have managed to prove that the formation of the radical cation form of PANI is the governing stage affecting the rate of aniline electropolymerization in the presence of sulfonic polyacids [ 56 ]. Later, the monitoring of PPy electrosynthesis in the same environment confirmed the adequateness of this approach [ 90 ].…”

In this review, we have summarized the main advantages of the method of spectroelectrochemistry as applied to recent studies on electrosynthesis and redox processes of electroactive polymer composite materials, which have found wide application in designing organic optoelectronic devices, batteries and sensors. These polymer composites include electroactive polymer complexes with large unmovable dopant anions such as polymer electrolytes, organic dyes, cyclodextrins, poly(β-hydroxyethers), as well as polymer-inorganic nanocomposites. The spectroelectrochemical methods reviewed include in situ electron absorption, Raman, infrared and electron spin resonance spectroscopies.

“…Recently, polyelectrolytes have been successfully used as the dopants of conducting polymers to fabricate conducting composites [ 69 , 70 , 71 ]. Goel S [ 72 ] developed a simple template-free interface polymerization method to synthesize PPy nanofibers using HCl, FeCl 3 , p-toluenesulfonic acid (p-TSA), camphor sulfonic acid (CSA) and polystyrene sulfonic acid (PSSA) as dopants, respectively.…”

Owing to their special structure and excellent physical and chemical properties, conducting polymers have attracted increasing attention in materials science. In recent years, tremendous efforts have been devoted to improving the comprehensive performance of conducting polymers by using the technique of “doping.” Spherical polyelectrolyte brushes (SPBs) bearing polyelectrolyte chains grafted densely to the surface of core particles have the potential to be novel dopant of conducting polymers not only because of their spherical structure, high grafting density and high charge density, but also due to the possibility of their being applied in printed electronics. This review first presents a summary of the general dopants of conducting polymers. Meanwhile, conducting polymers doped with spherical polyelectrolyte brushes (SPBs) is highlighted, including the preparation, characterization, performance and doping mechanism. It is demonstrated that comprehensive performance of conducting polymers has improved with the addition of SPBs, which act as template and dopant in the synthesis of composites. Furthermore, the applications and future developments of conductive composites are also briefly reviewed and proposed, which would draw more attention to this field.
