Hybrid Superparamagnetic Materials Based on Polyphenoxazine

摘要

Hybrid metal-polymer nanocomposite materials based on polyphenoxazine (PPhOA) and Fe_3O_4 nanoparticles were obtained for the first time via in situ oxidative polymerization of phenoxazine (PhOA) in an aqueous solution of isopropyl alcohol in the presence of Fe_3O_4 nanoparticles. Obtained hybrid Fe_3O_4/PPhOA nanomaterials were characterized by means of Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), atomic absorption spectrometry (AAS), thermogravimetric analysis (TGA), as well as by vibrating sample magnetometry. Magnetic and thermal properties of obtained nanocomposites were investigated.
