“…1a, these methods usually use graphite as the cathode and the metal as the anode, then apply voltage or current between the two electrodes to achieve anodization of the theory to explain the formation of PAA, which provided a reference for the formation theory about iron oxides, zirconium oxides, titanium oxides and other PAO. 21,36,[53][54][55][56][57][58][59] This theory believes that the FAD reaction plays a major role in the formation of the nanotubes.…”

“…The research on the mechanism of anodic oxides originated from the exploration of the phenomenon that two structures of compact layer and PAA formed by anodization of aluminum under different conditions. So far, many scholars have cited the formation mechanism of PAA to try to explain the growth process of ATNTs and other PAO which had a profound impact on the development of the later theory 28,[53][54][55].…”

“…A step forward in the fabrication of AANTs defining in detail the relation between current/voltage input and geometrical features of nanotubes was reported by Domagalski et al [ 164 ]. Apart from defining the relation between pulse duration and the resulting nanotube length, they discovered that current density during hard anodization pulse can affect the outer diameter and the surface charge of AANTs, contributing a higher control of the process and enabling tailor-engineering of anodic alumina nanotubes.…”

The development of aluminum anodization technology features many stages. With the story stretching for almost a century, rather straightforward—from current perspective—technology, raised into an iconic nanofabrication technique. The intrinsic properties of alumina porous structures constitute the vast utility in distinct fields. Nanoporous anodic alumina can be a starting point for: Templates, photonic structures, membranes, drug delivery platforms or nanoparticles, and more. Current state of the art would not be possible without decades of consecutive findings, during which, step by step, the technique was more understood. This review aims at providing an update regarding recent discoveries—improvements in the fabrication technology, a deeper understanding of the process, and a practical application of the material—providing a narrative supported with a proper background.

“…It has become an important research direction in the field of nanoscience to prepare PAA templates with a special structure by an effective process, which is favored by researchers . Because of the controllability and flexibility of preparation conditions, the PAA templates with special structures can be prepared by changing the conditions of anodization . Traditionally, there are two ways to prepare PAA films: mild anodization (MA) and hard anodization (HA).…”

Porous anodic alumina (PAA) films with periodically modulated pore diameters are prepared by cyclic anodization of Al in a 0.6 M H 3 PO 4 solution at room temperature. Studies have demonstrated that the oscillating current signals have an important effect on the structures of PAA films. Scanning electron microscopy (SEM) images of the PAA film show that when the positive triangle wave current signal is applied, with the increase in the maximum current value, PAA gradually exhibits a symmetrically modulated pore diameter structure, and part of the pores generates slub-like branches. When the maximum current value is 60 mA, the effect of modulation on the pore diameter is the most obvious and the UV reflectance spectrum shows the lowest reflectivity. A sawtooth wave current signal will cause the generation of a V-shaped structure at the junction of adjacent oxide layers. This work provides important guidance for regulating the structure of PAA by changing the current signal.
