Abstract

Polyaniline is one of the most well studied conducting polymers due to its advanced electrical, chemical, redox and morphological properties. The high conductivity of regular polyaniline, when partially oxidized and doped under acidic conditions, has been associated with the formation of unique electronic states known as polarons and bipolarons. Alternative aniline oxidation products and interesting nanotube and nanorod forms have been observed as the synthesis conditions are varied. Solid-state NMR has offered great opportunities for structural investigations and the determination of molecular dynamics in such a complex and diverse material. This review summarizes various applications of solid-state NMR techniques to polyaniline and its derivatives and the information that can be obtained by solid-state NMR.

摘要

聚苯胺是研究得最多的导电聚合物之一，因为它具有先进的电学、化学、氧化还原和形态学特性。在酸性条件下部分氧化和掺杂时，常规聚苯胺的高导电性与独特的电子态的形成有关，这些电子态被称为极化子和双极化子。随着合成条件的变化，已经观察到苯胺氧化产物的替代物以及有趣的纳米管和纳米棒形式。固态 NMR 为结构研究和如此复杂多样的材料中的分子动力学的确定提供了极好的机会。本文综述了固态 NMR 技术在聚苯胺及其衍生物中的各种应用以及通过固态 NMR 可以获得的信息。
