本文以氧化铝模板的孔洞为模型利用直流电沉积法制备了镍纳米线。采用SEM,XRD,TEM对镍纳米线的形貌和结构进行了表征。结果表明镍纳米线为单晶结构，沿[111]方向择优取向。把所制备的镍纳米线与石蜡按质量比1:1均匀混合后，利用同轴法测量其磁导率和介电常数，同时研究了该复合材料的吸波性能，计算得到了在不同厚度下的反射率曲线。研究发现该纳米线/石蜡复合材料是一种介电损耗材料，在约9.5GHz处介电损耗可达0.55，具有一定的吸波性能，当厚度为3mm时，在6.5GHz处反射率可达－18dB。
Nikel nanowires were prepared by direct current electrodeposition within the nanopores of anodic alumina membrane (AAM). The topography and texture of the nanowires were characterized by SEM, XRD, TEM. It is found that the nickel nanowires are the structure of single crystalline with a preferred orientation along the [111] direction. It is demonstrated that the nickel nanowires are dielectrical dissipation materials in the microwave electromagnetic experiment, the value of dielectrical dissipation is 0.55 at 9.5GHz. The nickel nanowires are considered as a candidate for microwave absorbing material.
