As the low-weight alternative of metals for conductivity-based applications, intrinsically conducting polymers with conjugated chain structures are critically important materials in modern society. They have been used not only in electronics to replace metals but also in a wide range of new applications, such as printing electronic circuits, transparent displays, solar cells, and radar-absorptive coatings on stealth aircraft. The first type is polyanilines co-doped with multiple acids, which are prepared by copolymerization of salts of aniline with different acids. The second type is poly(ethylene oxide)-grafted polyanilines and polydiphenylamines. The third type is grafted copolymers with non-conjugated backbones and conducting grafts. It should be noted that although the soluble conducting polymers demonstrated in the articles are based on polyanilines or polydiphenylamines, the corresponding synthetic strategies can be applied to the preparation of soluble conducting polymers with other types of structural units.
