Abstract
A hybrid dispersed magnetic nanomaterial of a core-shell structure with a core of Fe3O4 particles and a shell of polydiphenylamine-2-carboxylic acid is obtained for the first time. According to TEM data, Fe3O4/polydiphenylamine-2-carboxylic acid nanoparticles have dimensions 4 < d < 14 nm. By means of IR spectroscopy, it is established that the polymer shell is formed via C-C added to 2- and 4-positions of phenyl rings with respect to nitrogen. It is found that obtained nanocomposite material is superparamagnetic and highly thermally stable.
