Data from: The effect of ethylene glycol on pore arrangement of anodic aluminum oxide prepared by hard anodization

The influence of ethylene glycol (EG) addition on pore self-ordering process in anodic aluminum 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, which revealed that a smaller pore size can be obtained as EG concentration reaching 20 wt% in aqueous electrolyte. The number of estimated defects of AAO increase significantly with additive EG concentration at 50 wt%. Excellent ordering pore was realized when the samples were anodized in the 30 wt%-EG-containing aqueous electrolyte.electrolyte. The number of estimated defects of AAO increases significantly upon the added EG concentration reaching 50wt%. Excellent ordering pore was achieved when the samples were anodized in a 30wt%-EG-containing aqueous electrolyte.

本研究探究了乙二醇（ethylene glycol，EG）添加量对硬阳极氧化（hard anodization，HA）法制备的阳极氧化铝（anodic aluminum oxide，AAO）膜的孔自有序过程的影响。结果表明，EG对AAO的孔排布具有显著影响：当水性电解液中EG浓度达到20 wt%时，可获得更小的孔径；当EG添加浓度升至50 wt%时，AAO的估算缺陷数量显著增加；而当样品在含30 wt% EG的水性电解液中进行阳极氧化时，可实现优异的孔有序结构。
