二氧化硅纳米线已被证明具有特殊的机械性能。然而，到目前为止，通过一种容易实现的胶体方法制备直径小于20 nm的纳米粒子一直存在问题。在这项工作中，我们展示了一种新型的铁基表面活性剂如何容易地形成棒状胶束结构，这种结构可以用来模板形成直径小于5 nm的二氧化硅纳米线。
Silica nanowires have been shown to have exceptional mechanical properties. However, to date, their preparation with diameters less than 20 nm by an easily implemented colloidal method has been problematic. In this work, we show how a novel iron based surfactant readily forms rodlike micelle structures which may be used to template the formation of silica nanowires with diameters less than 5 nm.
