Synthesis of Polystyrene Nanowires Doped with Iron Oxide Nanoparticles Using a Pulsed Laser

We have developed a technique to synthesize polystyrene (PS) nanowires doped with iron oxide nanoparticles (nanoFeO) by sub-nanosecond pulsed laser irradiation. Scanning electron microscopy (SEM) images of the polymer nanowires with uniform diameters were obtained. The structure of the nanoFeO-PS nanowires was analyzed by scanning transmission electron microscopy (STEM) and energy-dispersive X-ray analysis (EDX). The polymer nanowires grew perpendicular to the surface of the source film, which contained iron oxide nanoparticles and dye molecules as a photoabsorber.
