Electronic Structure of Polianylinine Modified by Copper and Zirconium Salts

The features of the electronic structure and chemical bonds of PANI/Me composites (Me-Cu, Zr) have been studied spectroscopically. X-ray absorption spectroscopy, x-ray photoelectron spectroscopy, and infrared spectroscopy have been used for the research. It has been found that polyaniline is in a partially oxidized form in composites regardless of the type of modifying additive used, but it is more oxidized in PANI/Zr than in PANI/Cu. The chemical states of nitrogen in composites have been determined and the ratio of neutral and charged nitrogen groups is different.
