我们在铝衬底上制作了不同参数条件下的阳极氧化铝(AAO)模板。通过改变初次阳极化时间来得到不同尺寸的纳米孔。改变初次阳极化时间可容易地调节,而使用刻蚀技术又可以控制氧化铝孔的长度。在该研究中,控制阳极极化和刻蚀参量成功地制备了不同直径和不同长度的AAO纳米孔。在AAO模板的竖直沟道中生长了方向性强的碳纳米管,而AAO纳米孔的直径和长度可以控制这一过程。通过二次阳极极化法制备了有着六边形孔洞排列方式的纳米AAO模板。由于AAO纳米孔的直径和长度依赖于阳极化参量,故通过控制阳极化参量就可控制AAO纳米孔的直径和长度。
We fabricated anodized aluminum (AAO) templates on aluminum substrates with different parameters. By changing the initial anodization time to get different size nanopores. Altering the initial anodization time can be easily adjusted, and the use of etching techniques can in turn control the length of the alumina pores. In this study, AAO nanopores of different diameters and different lengths were successfully prepared by controlling anodic polarization and etching parameters. Directional carbon nanotubes were grown in the vertical channel of the AAO template, while the diameter and length of AAO nanopores controlled this process. The nano-AAO template with hexagonal arrangement of holes was prepared by the secondary anodic polarization method. Because the diameter and length of the AAO nanopore depend on the anodization parameters, the diameter and length of the AAO nanopore can be controlled by controlling the anodization parameters.
