Abstract

The crystal and local atomic structures of cobalt nanoparticles in a polymer material have been studied by X-ray absorption spectroscopy and X-ray diffraction. The polymer matrix of the samples was an acrylic acid (AA)—ethyl methacrylate (EMA) copolymer. The cobalt content of the samples was 20.45–50.70 wt %; the AA: EMA ratio in the polymer varied from 1: 10 to 1: 100. The structure of cobalt nanoparticles has been determined. Correlations have been revealed between the oxide-to-metal ratio in nanoparticles and the composition of nanocomposite polymer materials.
