摘　　要：文章在草酸电解液中,采用电化学氧化法在同一片铝箔上制备了具有多种微观结构的新型氧化铝模板。首先使阴极碳棒和阳极铝片成一定夹角,通过一次氧化过程在同一片铝箔上得到了具有不同孔径和孔深的2个区域,且2个区域面积比可以通过控制阴极和阳极的夹角来调控。采用碳球作为阴极,通过一次氧化过程在同一片铝箔上制备了孔径和孔深由薄膜中心向外呈对称性递减的氧化铝模板。并分析了上述2种新型氧化铝模板微观结构的形成机理,该机理对于利用此类模板的限域作用一次性制备纵横比各异的一维纳米材料及其相关物性研究具有重要意义。New-style aluminium oxide templates with various microstructures were fabricated in oxalic acid electrolyte by electrochemical oxidation of a piece of aluminum foil. Firstly, keeping a certain angle between the cathode carbon rod and the anode aluminum foil, two areas with different holes on the same piece of aluminum foil were formed by one-step electrochemical oxidation. The area ratio of different holes was controlled through adjusting the angle between the cathode and the anode. Moreover, the aperture and hole depth of aluminium oxide templates, which were prepared by one-step electrochemical oxidation using spherical carbon electrode as cathode, diminished symmetrically outward from the center of the templates. The oxidation mechanism of the two new-style aluminium oxide templates was discussed. The results will help to the fabrication of one-dimensional nano-materials with different aspect ratio on the same piece of aluminum foil and research of physical property.
