摘要
为了能制备出有序的纳米线阵列,采用一次阳极氧化的方法,制备出了孔径在12.8～43.5nm之间的多孔有序的氧化铝模板.通过改变氧化液浓度、氧化电压、氧化温度等条件,可对氧化铝模板的孔径大小进行控制,对各阳极氧化工艺因数对模板孔径的影响机理也进行了分析讨论.结果表明,在较低的氧化液浓度,氧化电压和氧化温度条件下,氧化铝膜的孔径较小;而在高的氧化液浓度,氧化电压和氧化温度条件下,氧化铝膜的孔径较大.
In order to fabricate ordered nanowires, nanometer-scale porous ordered alumina templates with the pore size of 12.8nm to 43.5nm by one-step anodic oxidation were prepared. The pore size can be adjusted by altering anodic voltage,oxidizing temperature and concentration of electrolyte solutions. The influence of parameters on the size of the pores was also analyzed and discussed. The result shows that the pore size of the alumina template would become smaller when it under the condition of lower anodic voltage,concentration of electrolyte solution and oxidizing temperature. While under the condition of higher anodic voltage, concentration of electrolyte solution and oxidizing temperature the pore size would become bigger.
