Flexible magnetic nanocomposite fibers were produced by an electrospinning method using
a polymeric solution containing poly(acrylonitrile) and magnetite nanoparticles. The educational
objective of this study was to demonstrate nanomanufacturing to undergraduate students in the College
of Engineering at Wichita State University (WSU). Magnetic nanoparticles (~10 nm) were prepared
using 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). This experimental study indicated that the average diameter of the magnetic
nanocomposite fibers ranged from 400 nm to 1.0 μm. The magnetic responses were found to increase
linearly with increasing percent loading of the magnetic nanoparticles.
