Flexible magnetic nanocomposite fibers were produced by electrospinning method using a polymeric solution containing poly(acrylonitrile) and magnetite nanoparticles. Magnetic nanoparticles (∼10 nm) were prepared by a chemical co-precipitation of ferric and ferrous chloride salts in the presence of an ammonium hydroxide solution. The effect of magnetic particle concentrations (e.g., 0%, 1%, 5%, 10%, 20% and 30%) on nanocomposite fibers, distribution and morphology were studied using scanning electron microscopy (SEM). The experimental study indicated that the average diameters of the magnetic nanocomposite fibers were between 400 nm and 1.08 μm. The magnetic responds were also found to increase linearly with increasing percent loading of the magnetic nanoparticles. It is concluded that this study provides promising results for various applications, such as filtration and separation of micron and nanosize organic and inorganic particles, HF antenna fabrication and biomedical.
