摘要：

Fabrication of ordered porous anodic alumina (PAA) with ultra-large interpore distances (D-int) is still a great challenge because of the occurrence of the breakdown or burning during anodization under ultrahigh voltages. Herein, the anodizing of aluminum at ultrahigh voltages (600-800 V) is realized in a series of mixed electrolytes consisting of solutions of citric acid in ethylene glycol and aqueous phosphoric acid solutions. Ordered FAA and patterned Al substrate with ultra-large D-int (1400-2036 nm) have been fabricated by two-step anodization on unpolished substrates successfully. (C) 2014 Elsevier Ltd.
