摘要: 将适量的有机溶剂加入电解液中,在15 ℃左右制备得到孔径大于200 nm的氧化铝模板.该法使电解时间缩短,加快了制备模板的过程, 是氧化铝模板的有效制备方法.将该方法与传统方法相结合,可以制备孔径在20~250 nm间的氧化铝模板. 实验表明:有机溶剂的加入可有效避免电解时热量的迅速产生, 通过改变实验条件可调控氧化铝模板的孔径.

Abstract: Alumina templates with large-size pores ( > 200 nm) were fabricated by adding organic solvent to electrolyte at 15 ℃. This effective method can shorten electrolysis time and quicken the process of the template preparation. A series of templates with different diameters (20~250 nm) were obtained by the combination of this method and traditional one. Experiment results show that the addition of organic solvent can efficiently avoid the heat produced quickly in the process of electrolysis. Pore diameter of alumina templates relys on controlled the experiment condition.
