Hybrid magnetic nanomaterial with core-shell structure, where particles of Fe3O4 form the core and polydiphenylamine-2-carboxylic acid is
the shell, was obtained for the first time in the interfacial process. According to TEM data Fe3O4/polydiphenylamine-2-carboxylic acid
nanoparticles have size 2 < d < 14 nm. It was found by IR spectroscopy that the polymer shell is formed by C–C - joining into 2- and 4-
positions of phenyl rings with respect to nitrogen. The obtained hybrid nanomaterial is superparamagnetic and thermally stable.

Key words: interfacial polymerization in situ; core-shell; Fe3O4/polydiphenylamine-2-carboxylic acid hybrid nanoparticles; magnetic nanomaterials; magnetic fluids
