dc.description.abstract Nanocomposite polyethylene oxide (PEO) fibers containing magnetic domains were produced using parallel plate electrospinning. The fibers were spun from solutions dosed with nanoparticles of magnetite (Fe3O4) in 2wt% PEO in water. Solution parameters like viscosity, conductivity, and surface tension were measured and correlated to final fiber diameter. Increased amounts of magnetic nanoparticles produced higher conductivity, higher viscosity, and lower surface tension solutions. Transmission electron microscopy and energy dispersive spectroscopy were used to analyze the diameters of the nanofibers as well as the distribution of the magnetic nanoparticles inside the PEO matrix. A SQUID magnetometer was applied to determine the AC and DC magnetic susceptibility of the fibers. The resultant nanofibers had diameters as low as 100 nm and exhibited unique AC susceptibility patterns and magnetic responses making them excellent for anti-counterfeiting applications. en_US
