采用两步电沉积法成功制备了有序的Ni/Cu壳/核结构纳米电缆阵列。首先，在纳米多孔阳极氧化铝（AAO）模板上化学电沉积镍（Ni）纳米管。然后以AAO/Ni纳米管复合膜为二次模板，在Ni纳米管中沉积存款铜（Cu）纳米线。纳米电缆的形态和微观结构的特征在于使用扫描电子显微镜和透射电子显微镜。纳米电缆的化学组成已通过X射线衍射证实。磁化强度测试表明，Ni/Cu纳米电缆阵列具有较高的剩磁比。
Ordered Ni/Cu shell/core structured nanocable arrays were successfully fabricated by a two-step electrodeposition process. First, nickel (Ni) nanotubes were obtained by chemical electrodeposition in nanoporous anodic aluminum oxide (AAO) template. Then the AAO/Ni nanotube composite membrane was used as a secondary template to deposit copper (Cu) nanowires into Ni nanotubes. The morphology and microstructure of the nanocables has been characterized using scanning electron microscopy and transmission electron microscopy. The chemical composition of the nanocables has been confirmed by X-ray diffraction. Magnetization measurements revealed that Ni/Cu nanocable arrays have a high remanence ratio.
