摘　　要：以多孔氧化铝为样模 ,运用电沉积法向样模的微孔中沉积金属Ni,制备得到了有序排列的金属Ni纳米线阵列 ;以透射电镜为主要表征手段 ,系统地研究了多孔氧化铝样模的制备条件以及电沉积条件对金属Ni纳米线尺寸的影响 ;结果表明 :制备多孔氧化铝样模过程中的氧化介质、氧化温度、氧化电压以及氧化后的扩孔时间影响Ni纳米线的直径和长度 。Ordered metal Nickel nanowire arrays were obtained by electro deposition on porous alumina template.The effective factors in preparation and deposition processes on the nanowire size were investigated systematically by means of TEM.The results show that medium,voltage and temperature in oxidation during the template preparation and the pore widening duration after oxidation would influence the diameter and length of the nanowires.Time and voltage in electro deposition influence mainly the length of nanowires.
