Резюме: Magnetic nanoparticles based on Fe3O4 and polydiphenylamine-2-carbonic acid (PDPhACA) with core-shell structure, where Fe3O4 is the core and PDPhACA is the shell, were obtained for the first time. Influence of polymerization conditions (reagents concentration, their ratio, temperature of the reaction) on the yield and structure of polymers was studied. Formation of nanoparticles was proved by X-ray diffraction analysis and transmission electron microscopy. On X-ray images one can clearly identify diffraction peaks of Fe3O4 nanoparticles. Fe3O4/PDPhACA nanoparticles dimensions fall in the limits of 4<d<14 nm. Magnetic properties of Fe3O4/PDPhACA nanoparticles were studied. It was found that obtained nanoparticles are superparamagnetic.
