Abstract

The influence of the addition of ethylene glycol (EG) on the pore self-ordering process in anodic aluminium oxide (AAO) membranes prepared by hard anodization (HA) was investigated. It was illustrated that EG has a substantial effect on the pore arrangement of AAO, and it was found that a smaller pore size can be obtained with an EG concentration reaching 20 wt% in aqueous electrolyte. The number of estimated defects of AAO increases significantly with an increase in EG concentration to 50 wt%. Excellent ordering of pores was realized when the samples were anodized in the 30 wt%-EG-containing aqueous electrolyte.

摘要

研究了添加乙二醇（EG）对硬阳极氧化（HA）制备的阳极氧化铝（AAO）膜中孔自有序化过程的影响。结果表明，EG对AAO的孔排列有显著影响，发现在水电解质中EG浓度达到20 wt%时可获得更小的孔径。随着EG浓度增加到50 wt%，AAO估计的缺陷数量显著增加。当样品在含30 wt%EG的水电解质中进行阳极氧化时，实现了优异的孔有序排列。
