Abstract

X-ray absorption near edge structure spectroscopy (XANES; NEXAFS is used for soft X-rays) and X-ray photoelectron spectroscopy (XPS) are used to study the local structure of the PANI/Cu nanocomposite obtained in the polymerization of aniline by chemical oxidation in the presence of copper-chloride dihydrate without the addition of acid. Copper in the composite is divalent and copper atoms with different local environments are present. Polyaniline is oxidized and protonated during the formation of the nanocomposite. Protonation occurs through imine groups.

X射线光谱研究PANI / Cu纳米复合材料的原子和电子结构

摘要

X射线吸收近边缘结构光谱法（XANES； NEXAFS用于软X射线）和X射线光电子能谱法（XPS）用于研究苯胺通过化学方法聚合得到的PANI / Cu纳米复合材料的局部结构在二水合氯化铜存在下进行氧化，无需添加酸。复合物中的铜是二价的，并且存在具有不同局部环境的铜原子。聚苯胺在纳米复合材料的形成过程中被氧化和质子化。质子化通过亚胺基发生。
