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.

Key words: Alumina template, Organic solvent, Pore diameter
