“…Then, the glass slide was electrochemically anodized to form porous Al 2 O 3 . As reported in previous studies, the anodic aluminum oxide grown at room temperature possesses amorphous structure [65,[69][70][71][72]. After anodization, the samples were etched to increase the porosity.…”

Nanostructured thin films have gained great interests in recent years due to their significantly enhanced properties and great potential for various applications. Nanoindentation techniques are commonly used to measure nanomechanical properties of thin films and the surface layers of bulk materials. In this article, nanoindentation tests coupled with computer modeling were proposed to characterize nanostructured porous anodic aluminum oxide (AAO) films grown on glass. A three-dimensional nanoindentation model was developed. The Young's modulus and hardness were measured by nanoindentation using a Berkowich pyramidal sharp tip indenter. The effects of the substrate and porous structure of the film on the coating measurements were investigated. The dilemma for extracting the mechanical properties of a porous structural film in nanoindentation has been pointed out, and an alternative approach of combined modeling/experimental provided a justification by considering the porous structure of the film and minimizing the influence of the substrate. Computer modeling results were validated by experimental data.

“…A recent study of porous alumina films formed in phosphoric [275,292], oxalic [293] and sulfuric [291] acids, showed that the originally formed anodic porous alumina films are definitely amorphous. On the other hand, anodizing in chromic acid can result in amorphous alumina with traces of g-Al 2 O 3 [291].…”

“…Recently, the mixing of both galvanostatic and potentiostatic regimes has been reported as a new and efficient method for the high-field anodization of aluminum [213,223,251,293,339]. The sample was pre-anodized at a constant current density and, after a certain period of time and after reaching a specified potential, the potentiostatic mode was switched.…”

“…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.…”
