中文摘要: 在H2SO4电解液中对高纯铝箔进行阳极氧化，考察分析了电解液浓度对多孔阳极氧化铝膜的影响，结果表明：随硫酸电解液浓度的增加，纳米孔孔径逐渐增大，孔密度降低，孔的有序性先提高后降低；采用23 V直流电压进行阳极氧化，电解液浓度为0.6~1.0 mol/L时制得的氧化铝膜孔径均匀性及有序度均较好，尤其以0.8 mol/L H2SO4最佳；阳极氧化铝膜的厚度随电解液浓度的提高而增大；电解液浓度过高易于将铝箔快速击穿。
Abstract:High-pure aluminum foil was anodic oxidated in H2SO4 electrolyte. Effects of electrolyte concentration on porous alumina film were investigated. The results indicated that aperture of nano-pore increased with the increase of electrolyte concentration, and the density of nano-pore reduced with the increase of electrolyte concentration, while the order of nano-pore improved first and then deteriorated with the increase of electrolyte concentration. When aluminum foil was anodic oxidated at 23 V direct voltages, the better uniformity of aperture and order of alumina film was achieved in 0.6 ~ 1.0 mol/L electrolytes, especially in 0.8 mol/L H2SO4. The thickness of alumina film increased with the increase of electrolyte concentration. Exorbitant electrolyte concentration was prone to rapid breakdown the aluminum foil.
