Abstract

The synthesis of the title matrix-mediated nanocomposite was performed in both poly(4-vinylpyridine) homopolymer and vinylstyrene-4-vinylpyridine copolymers. NH2–NH2 was used as the reducing agent to prepare the polymer-supported metallic particles which were later converted into fine oxide powders by oxidation. The structure and morphology of the products were studied by Fourier transform infrared spectroscopy, wide angle X-ray diffraction, transmission electron microscopy as well as electron spectroscopy for chemical analysis and magnetic measurements. The wide angle X-ray diffraction patterns contained reflections that could be assigned to Fe3O4 particles while no reflections were observed that correspond to ultrafine iron powders. The magnetization behaviour of the nanocomposite was determined by the degree of loading of Fe in the polymer matrix.
