Abstract

Ordered anodic porous alumina with large-scale periodicity was fabricated via phosphonoacetic acid anodizing. Aluminum specimens were anodized in a 0.1–0.9 M phosphonoacetic acid solution under various electrochemical operating conditions, and optimum anodizing at 205–225 V exhibited self-ordering growth of the porous alumina. These self-ordering voltages during phosphonoacetic acid anodizing filled an undiscovered vacant region in the linear relationship between the self-ordering voltage and the cell diameter. The nanostructured aluminum surface formed via self-ordering phosphonoacetic acid anodizing produced a bright structural coloration with a visible light wavelength of 500–700 nm, which is useful for optical nanoapplications. © The Author(s) 2015.

磷酸乙酸中自有序铝阳极氧化及其结构着色

采用磷酸乙酸阳极氧化法制备了具有大尺度周期性的有序阳极多孔氧化铝。在0.1 ~ 0.9 M的磷酸乙酸溶液中，在不同的电化学操作条件下对铝试样进行阳极氧化，在205 ~ 225 V的最佳阳极氧化条件下，多孔氧化铝呈现自有序生长。磷酸乙酸阳极氧化过程中的自序电压填补了自序电压与电池直径线性关系中一个未被发现的空白区域。在可见光波长为500 ~ 700 nm的范围内，经磷酸乙酸阳极氧化形成的纳米结构铝表面具有明亮的结构色，可用于光学纳米应用。©作者2015。由ECS出版。这是一篇在知识共享署名非商业禁止衍生品4.0许可(CC BY-NC-ND, http://creativecommons.org/licenses/by-nc-nd/4.0/)条款下发布的开放获取文章，该许可允许在任何媒介上进行非商业重用、分发和复制，前提是原始作品不以任何方式改变并适当引用。如需商业使用许可，请发邮件至oa@electrochem.org。[DOI: 10.1149/2.0021508ssl]版权所有
