Abstract

Hybrid inorganic–organic nanocomposite materials are of current interest because of their multi functionality, ease of processability, and potential for large-scale manufacturing.  Here the monomer pyrrole was polymerized in an aqueous acidic medium in the presence of nano dimensional magnetite (Fe3O4) using ammonium peroxodisulphate (APS) as oxidant. Characterization of the composites was carried out by x-ray diffraction, fourier transform infrared spectroscopy. The surface morphology was investigated by scanning electron microscopy (SEM), and transmission electron microscopy (TEM) analysis. TEM studies revealed the presence of Fe3O4 nanoparticles encapsulated by polypyrrole (PPY) with size in the range of 20 to 30 nm. The magnetization data exhibit a small hysteresis loop at room temperature. The Mössbauer spectra at room temperature reveal the doublet structure, characteristic of the superparamagnetic phase in magnetite (Fe3O4).
