| Popis: | A simple method for preparation of hybrid magnetic nanocomposites consisting of bimetallic Co–Fe nanoparticles and polyphenoxazine (PPOA) is described. The nanocomposites were prepared by IR heating of precursors based on PPOA, cobalt (II) acetate, and iron (III) chloride in an inert atmosphere at T = 400–600 °C in a short time (2–10 min). Hybrid nanomaterials were characterized by means of X-ray diffraction, Fourier transform infrared spectroscopy, elemental analysis, thermogravimetric analysis, differential scanning calorimetry, transmission and field emission scanning electron microscopy, atomic absorption spectrometry, and vibrating sample magnetometry. Based on the value of hysteresis loop squareness (k S = 0.021–0.034), it was concluded that almost 100% of Co–Fe nanoparticles in the nanocomposite are superparamagnetic. |
