Uniform and bead-free magnetic polyvinyl alcohol/iron oxide (PVA/Fe3O4) nanocomposite fibers were prepared by electrospinning. The morphology was systematically optimized by changing the electrospinning parameters including polymer concentration, iron (II, III) nanoparticles loading, applied voltage, tip-to-collector distance and flow rate. All these parameters are shown to affect the fiber morphology to some extent. Rheological studies revealed a Newtonian behavior of PVA and PVA/Fe3O4 solutions. The influence of Fe3O4 NPs on thermal properties of PVA fibers was characterized by thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). With incorporation of magnetic Fe3O4 NPs, the nanocomposite fibers exhibit magnetic properties. The PVA based magnetic fibers prepared here are thought to be suitable for various applications.
