The structure and composition of the nanocomposite based on the mixture of natural polyamide base and FeO filler, some physico-chemical properties were studied using elemental analysis, IR-spectroscopy, X-ray phase analysis, quantum-chemical calculations, thermal analysis, UV spectroscopy methods. Studies were conducted to study the chemical composition of the initial components and compositions. The mole ratio of polyamide and iron particles filled into it was determined. Based on the results of thermal analysis, the liquefaction, decomposition temperatures and thermal stability of the composite were studied. Changes in vibration frequencies of carbonyl and amino groups in the polyamide base were observed with the help of the obtained IR-spectra. It was found that the stabilization of FeO polyamide by base occurs through these groups.
