| 摘 要： | 以草酸为电解液，分别用一次阳极氧化法和二次阳极氧化法制备了阳极氧化铝（AAO，anodic aluminum oxide）模板，在较大范围内得到了纳米孔分布均匀、孔洞大小均一、尺寸可控、排列有序的双通模板．采用扫描电镜（SEM）对其形貌进行表征，发现一次阳极氧化法制得的AAO模板的反面孔洞排列较为规则，而正面的孔洞排列规则性明显不如反面；二次阳极氧化法制备得到的模板正、反面孔洞的排列都比较规则．比较了模板正、反面纳米孔洞的差异，并结合阳极氧化过程中电流的变化，探讨了自组织孔洞的形成机理．目前尚未发现关于纳米孔洞差异性及原因分析的文献报道．

| Abstract: | Anodic aluminum oxide(AAO) templates were prepared by one-and two-step anodization in oxalic acid solution,respectively.The morphology of the AAO templates were characterized by scanning electron microscopy(SEM) and the result showed that the two-side-open templates have ordered,regular and diameter-controlled nano-pores.It can be seen from the SEM images of the AAO templates that the nano-pores in the back side of the AAO template prepared by one-step anodization were more regular than that in the face sid... |
