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