摘要: Abstract Polymeric hybrid materials were synthesized via chemical oxidation polymerization. Process was carried on the surface of magnetic nanoparticles, (prepared separately) where initiator (Fe3+ ions) located. The structure resulting nanocomposite investigated in detail by means X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). hydrodynamic size morphology evaluated scanning electron microscopy (SEM) dynamic light scattering (DLS). polymeric shell controlled, using TGA analysis together with TEM characterization. Magnetic properties PRHD@CoFe2O4 nanomaterials studied a wide range temperature fields up to 120 kOe. determine what extent PRHD separates magnetically CoFe2O4 nanoparticles influences their properties. cytotoxicity tested against mouse macrophage (J774. E) human osteosarcoma cell line (U2OS). Additionally, sensitivity bacteria Escherichia coli ATCC 8739 Staphylococcus aureus 25923 Kirby-Bauer disc method.
