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.

聚合物纳米线由于其优异的电学、磁学和光学特性，在气体传感器、激光器和有机场效应晶体管中的出色应用而备受关注。新型聚合物纳米线的制备方法对于实现未来纳米技术的应用非常重要。我们成功地通过亚纳秒脉冲激光照射生成聚合物纳米线，并测量了大气压下直径均匀的聚合物纳米线生长的时间分辨图像。利用该方法还成功合成了纳米FeO掺杂的PS纳米线。提出了聚合物纳米线合成的合理机制。预计未来它将在分子器件和超高灵敏度传感器的制造等广泛的应用领域得到应用。
