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 alu-minum 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.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 side, but the nano-pores in the two surfaces of the AAO templates prepared by two-step anodization were all regular. The difference of the nano-pores in the face and back side was compared and the plot of the current vs. the time during anodization was recorded. The mechanism of the self-organization process of the nano-peres of the AAO templates was discussed. Up to now, there is no paper to explain the difference of the nano-pores.
