【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。
[Abstract]:In this paper, a new aluminum oxide template with various microstructure was prepared on the same aluminum foil by electrochemical oxidation in oxalic acid electrolyte.Firstly, the cathode carbon rod and the anode aluminum sheet are made into a certain angle, and two regions with different pore sizes and hole depths are obtained on the same aluminum foil by one oxidation process, and the area ratio of the two regions can be controlled by controlling the angle between the cathode and the anode.Using carbon ball as cathode, the aluminum oxide template with decreasing pore size and pore depth from the center of the film to the outside was prepared by one oxidation process on the same aluminum foil.The formation mechanism of the microstructures of the two new types of alumina templates is also analyzed. The mechanism is of great significance for the one-dimensional nanomaterials with different aspect ratios and their related physical properties by using the limiting effect of these templates.
