| Research Abstract |
Polymer nanowires have much attention for their excellent use in gas sensors, lasers, and organic field-effect transistors owing to their excellent electrical, magnetic, and optical properties. The production method of novel polymer nanowires is quite important for realizing future nanotechnology applications. We have succeeded in generation of polymer nanowires by sub-nanosecond pulsed laser irradiation and time-resolved images of the growth of polymer nanowires with uniform diameters at atmospheric pressure were measured. Also nanoFeO-doped PS nanowires were successfully synthesized using this method. A plausible mechanism of polymer nanowire synthesis was proposed. It is expected to be utilized in a wide range of application fields such as in the fabrication of molecular devices and ultrahigh-sensitivity sensors in the future.
