在无模板的条件下使用均匀外加磁场进行诱导,得到了具有均匀的形貌、很大的长径比和多晶结构的镍纳米线,并使用SEM、TEM、XRD等检测手段对产物等进行了表征.实验证明,通过改变反应条件可以控制产物的形貌和尺寸,并分析了镍纳米线的生长机理.采用的方法无须使用模板,反应周期短,成本低,操作简单,适合大量制备,可以用于研究和工业生产.
Abstract：Even-shaped nickel nanowires with great length-diameter ratio and polycrystalline structure are prepared with no template through induction of applied uniform magnetic field.The products are characterized through scanning electron microscope,transmission electron microscope,X-ray polycrystalline diffractometer,et al.Further investigation is done to study the relations between reaction conditions and morphology and scale of the product.A possible mechanism of the growth of nickel nanowires is also discussed.Advantages of the method have template-free,low-cost,easy to operate,a short reaction period.And it is suitable for large-scale preparation.
