通过添加适量乙醇对草酸电解液进行改性,在40～180V阳极氧化电压下成功制备了孔间距大范围内可调的高度有序多孔氧化铝模板(100～445nm).结果表明,在本实验条件下,适量乙醇的添加可以有效抑止高电压阳极氧化过程中燃烧和击穿现象的发生;当阳极氧化电压在40～170V之间时,模板孔间距和电压之间呈现极好的线性关系;而当电压超过180V后,模板将会产生燃烧和击穿现象. Through the modification of oxalic acid electrolyte by adding appropriate amount of ethanol, a highly ordered porous alumina template (100 ~ 445nm) with adjustable pore-to-pore spacing was successfully prepared at anodic oxidation voltage of 40 ~ 180V.The results showed that in this experiment Under the conditions, the addition of appropriate amount of ethanol can effectively restrain the combustion and breakdown phenomena during the high voltage anodization. When the anodization voltage is between 40 and 170V, there is an excellent linear relationship between the pitch and the voltage of the template. When the voltage exceeds 180V, the template will produce combustion and breakdown phenomenon.
