Electronic structure of polyaniline modified with zirconium and copper salts

The results of spectroscopic studies of the electronic structure and chemical bonds of PANI – Me composites (Me – Cu, Zr) are presented. X-ray absorption spectroscopy, X-ray photoelectron spectroscopy, IR spectroscopy were used for research. It was established that regardless of which modifying additive polyaniline is used in composites is in partially oxidized form, however, in PANI – Zr is more oxidized than in PANI – Cu. The chemical states of nitrogen in the composites are determined; a different ratio of neutral and charged nitrogen groups is observed.
