원리
There are many methods for the synthesis of conductive polymers. Most conductive polymers are prepared by oxidative coupling of monocyclic precursors. Such reactions entail dehydrogenation:
- n H–[X]–H → H–[X]n–H + 2(n–1) H+ + 2(n–1) e–
The low solubility of most polymers presents challenges. Some researchers have addressed this through the formation of nanostructures and surfactant-stabilized conducting polymer dispersions in water. These include polyaniline nanofibers and PEDOT:PSS. These materials have lower molecular weights than that of some materials previously explored in the literature. However, in some cases, the molecular weight need not be high to achieve the desired properties.

생각보다 현재 개발되어있는, 또는 개발되고 있는 전도성 고분자의 종류가 많은 것 같다. 전도성 고분자는 금속만큼이나 활용성이 무궁무진한만큼 더 깊이 개발되었으면 좋겠다.
