在 30 摄氏度、20 至 60 V 的电压范围内，在 0.3 M 草酸中添加各种甘油（甘油体积的 0-100%）形成阳极氧化铝。结果发现，电解质的性质以及电压对形成的氧化物（多孔或无孔阻挡型氧化物）的类型及其排列有很大影响。 Quantitative arrangement analysis of the nanoporous oxide has been performed with the use of fast Fourier transforms of the FE-SEM images. The obtained data were confronted with criterion number estimated from the operating conditions and electrolytes properties.研究发现，纳米孔的最佳排列是当标准数接近其他水性电解质的文献数据时。 (C) 2014 Elsevier B.V. 保留所有权利。
Anodic aluminum oxide has been formed in 0.3 M oxalic acid with various additions of glycerol (0-100% vol. of glycerol) at voltage range from 20 to 60 V at 30 degrees C. It was found that properties of the electrolytes, as well as the voltage have strong influence on the type of formed oxide (porous, or non-porous barrier type oxide) and its arrangement. Quantitative arrangement analysis of the nanoporous oxide has been performed with the use of fast Fourier transforms of the FE-SEM images. The obtained data were confronted with criterion number estimated from the operating conditions and electrolytes properties. It was found that the best arrangement of the nanopores is when the criterion number is close to the literature data for other, aqueous electrolytes. (C) 2014 Elsevier B.V. All rights reserved.
