Stability of anodic aluminum oxide membranes with nanopores

Highly Ordered Anodic Porous Alumina Formation by Self‐Organized Anodizing

“…The thermal characteristics of highly ordered porous alumina structures formed on aluminum have been studied widely [299][300][301][302][303][304][305][306], with thermal analyses being performed in order to collect data on chemical resistance [299,300], structural and optical properties [292,[300][301][302][303], thermal conductivity and diffusivity along the channel axis [304], self-repair rearrangement of ordered nanopore arrays induced by long-term heat treatment [305], and mechanical properties [306]. The fracture mechanism, Youngs modulus, hardness, fracture toughness [306] and fracture behavior in cylindrical ordered porous alumina [307] were also investigated.…”

Polypyrrole nanotube array sensor for enhanced adsorption of glucose oxidase in glucose biosensors

“…As the feasibility of high enzyme loading and enhanced characteristics have been proved by using commercially available nano-porous alumina Anodisc TM s, the same nano-porous alumina membrane can be produced by using fabrication procedures reported by several researches (Redon et al, 2005;Yang et al, 2003;Yu et al, 2006) to optimize the pore size and electrode thickness to gain much improved performances of biosensors.…”

Contact angle studies on anodic porous alumina

“…AAO templates were prepared using the fabrication procedures reported by us and other research groups [5][6][7][20][21][22]. In this case, aluminum sheets (99.999%) (20 × 10 mm, thickness 0.13 mm) were annealed under air at 480 • C for 60 min and mechanically and electrochemically polished (1:5 v/v of EtOH/HClO 4 ) prior to anodization.…”

“…One of the most important methods for the preparation of 1D nanoscale materials is the template technique, which uses nanoporous membranes as templates [2][3][4]. In this method, anodic aluminum oxide membranes (AAO), prepared by electrochemical etching of aluminum foil in oxalic, sulfuric, and phosphoric acid solutions are the membranes most commonly used [5][6][7][8][9][10] for the fabrication of semiconductor nanowires, superconductor nanowire arrays, carbon nanotube arrays, etc. These materials have been fabricated mainly by electro [11][12][13] and electroless [14] deposition, chemical vapor deposition [15], and sputtering or evaporating of the material on the surface of the AAO at high temperatures [16,17]; however, attempts to fill the pores by gravity alone have resulted unfruitful.…”
