Multifunctional metal/oxide/metal core/multi-shell nanowire arrays were prepared mostly by physical or chemical vapor deposition. In our study, the Cu/CuO/Ni core/multi-shell nanowire arrays were prepared by AAO template-electrodeposition and oxidation processes. The Cu/Ni core/shell nanowire arrays were prepared by AAO template-electrodeposition method. The microstructure and chemical compositions of the core/multi-shell nanowires and core/shell nanowires have been characterized using transmission electron microscopy with HADDF-STEM and X-ray diffraction. Magnetization measurements revealed that the Cu/CuO/Ni and Cu/Ni nanowire arrays have high coercivity and remanence ratio.

多功能金属/氧化物/金属核/多壳纳米线阵列主要通过物理或化学气相沉积制备。在我们的研究中，通过AAO模板电沉积和氧化工艺制备了Cu / CuO / Ni核/多壳纳米线阵列。采用AAO模板电沉积法制备了Cu / Ni核/壳纳米线阵列。核/多壳纳米线和核/壳纳米线的微观结构和化学组成已使用具有HADDF-STEM的透射电子显微镜和X射线衍射进行了表征。磁化测量表明，Cu / CuO / Ni和Cu / Ni纳米线阵列具有高矫顽力和剩磁比。
