A comparative analysis was conducted on nine polyamide-6 (PA-6) composites prepared in an oil medium using Fe(CH₃COO)₂ as a precursor and the PA-52 control sample. The characterization was based on X-ray fluorescence (XRF), Fourier-transform infrared spectroscopy (FTIR), and spectral reflectance measurements over the 220–1400 nm wavelength range. The Fe₂O₃-equivalent content ranged from 0.0398 to 53.1 wt.%. The PA-55 sample exhibited an Fe₂O₃-equivalent content of 8.15 wt.% and a calculated polymer-rich remainder of 91.062 wt.%. FTIR analysis revealed an absorption maximum corresponding to the Amide I band at 1643.85 cm⁻¹, while a minimum spectral reflectance of 64.572% was recorded at 868 nm. Based on these findings, PA-55 was selected for further investigation. However, the phase composition of the resulting compounds and the nanoscale dimensions of the particles require additional verification using independent analytical methods.Keywords
