摘    要:对未经化学抛光处理的Al进行阳极氧化得到阳极氧化铝模板,发现Al表面形成了条纹与多孔阵列共存的自组织结构,用原子力显微镜对这种结构进行了研究.借助Brusselator模型对条纹的形成机理进行了讨论,认为条纹图案是Al表面氧化层/电解液界面的Al2O3在整个反应过程中的生成和溶解两个过程相互竞争导致的,只有在特定的反应条件才会出现高度有序的结构. 关键词: 氧化铝模板(AAO) 原子力显微镜(AFM) 自组织条纹 Brusselator模型

关 键 词:氧化铝模板(AAO)  原子力显微镜(AFM)  自组织条纹  Brusselator模型

Abstract:Non-polished aluminum sheets were anodized and the coexistence of self-assembled stripes and porous arrays on the Al surface was observed. The nanostructures were investigated in details using an atomic force microscope. And the formation mechanism of the stripes was discussed and simulated using Brusselator model in this work. We demonstrated that the self-assembled patterns on the Al surface were governed by the competition of formation and dissolution of alumina film during the reaction process. Moreover, this type of ordered structure could only form in certain conditions.
Keywords:anodic aluminum oxide (AAO)    atomic force microscope(AFM)    self-assembled strips  Brusselator model
