Fabrication of ordered porous anodic alumina with ultra-large interpore distances using ultrahigh voltages
چکیده انگلیسی


• Porous anodic alumina (PAA) can be formed on unpolished Al substrate.
• The interpore distance of PAA may extend to as large as 2036 nm.
• The anodizing voltage can reach up to 800 V.
• Fabrication of PAA under ultrahigh voltage does not need a very low temperature.

Fabrication of ordered porous anodic alumina (PAA) with ultra-large interpore distances (Dint) 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 PAA and patterned Al substrate with ultra-large Dint (1400–2036 nm) have been fabricated by two-step anodization on unpolished substrates successfully.
