“…1.22b, c). When a high enough U is applied during anodization, most of the O 2− is consumed and released in the form of O 2 due to the high J e accompanied by the high U [15,57,58,70]. Therefore the as-prepared porous AAO is mainly made up of Al(OH) 3 , AlOOH, and electrolyte anions, etc., and the inner layer (i.e., high purity Al 2 O 3 with relatively better chemical stability and mechanical strength) of the porous AAO often can't be observed.…”

“…1.22a). It has been known that the formation and dehydration of aluminum hydroxide (e.g., Al(OH) 3 ) will influence the microstructural morphologies of porous AAO to a large extent [56][57][58]70]. In this type, the as-prepared porous AAO are usually formed under a relatively lower U and J.…”

“…As the increase of U, more OH − and O 2− can be generated according to the (1.12), thus forming more Al (OH) 3 inside the porous AAO. Moreover, the higher U will promote the dehydration process of Al(OH) 3 , thus resulting in a relatively smaller ζ under the coaction of the compressive stress between adjacent cells and the volume contraction caused by the Al(OH) 3 dehydration [15,56,57,70,71], corresponding to the conventional so called HA processes [25,[53][54][55][56][57]. In addition, it worth mentioning that in type I, most of the Al(OH) 3 is formed and dehydrated at the outer , respectively.…”

Scale bars = 300 nm [15] layer of the unit cells, and the inner layer is almost made up of high purity Al 2 O 3 due to the different migration abilities of O 2− and OH − [15,[56][57][58]70]. Therefore, the unit cells of the as-prepared porous AAO is made up of inner layer and outer layer, and the fracture plane appears along the pores of the porous AAO [22, 24-26, 39-47, 54, 57].…”

The synthesis of nanoporous alumina based on anodization process is a field of active research. In this chapter, some fundamental scientific topics toward formation mechanisms of nanoporous alumina will be discussed in detail.(1) The intrinsic mechanisms of mild and hard anodization processes: the definition of mild anodization (MA) and hard anodization (HA); the critical condition between MA and HA processes. (2) The origins of self-ordering phenomenon: the structure models of nanoporous alumina; the influence of electrical field and internal stress. (3) The growth models of nanoporous alumina: the classical growth models of nanoporous alumina; the advantages and disadvantages of present models; the physical and chemical processes during aluminum anodization. (4) The intrinsic relationship between anodization conditions and anodization processes: the influence of anodization voltage and current density; the influence of electrolyte system; the influence of other anodization conditions. (5) Controllable fabrication of nanoporous alumina: the relationship between anodization conditions and structural parameters (e.g., interpore distance, pore size); fabrication of regular nanoporous alumina (i.e., with highly ordered pores); fabrication of nanoporous alumina with complex pore structure. In addition to nanoporous alumina, the findings and conclusions in this chapter may also be applied in other valve metal anodization processes (e.g., Ti, Zr, W anodization).

“…4,5 In the past years, porous anodic alumina thin films exhibited colored after undergoing anodic oxidation. [6][7][8][9] In addition, PAA with nanopores are popularly used as a template for the synthesis of various nanowires and nanotubes. 10,11 Zhao et al 12 constructed a PAA film embedded with carbon nanotubes (CNTs@PAA) on an Al substrate and found that infusion with water resulted in a significant color change.…”

Optical and magnetic properties of PAA@Fe nanocomposite films

A simple method to fabricate porous anodic alumina films embedded with Fe is reported. The films exhibit vivid structural colors and magnetic properties after being synthesized by an ac electrodeposition method. The optical properties of the samples can be effectively tuned by varying the oxidation time of aluminum. The coercivity mechanism of the Fe nanowires in our case is consistent with fanning reversal mode. PAA@Fe films can be used in many areas including decoration, display and multifunctional anti-counterfeiting applications. C 2013 Author(s)

The synthesis of flexible photonic materials, by sustainable and scalable methods, is proved to be a difficult task for the materials science and industrial communities. Alongside, the modern society has also grown a strong dependence on polymeric materials, demanding superpolymers that combine functionality and cost with superior after‐use properties. The path for accomplishing this aim is made possible by mimicking nature through the merging of self‐ordered nanostructures and a commodity thermoplastic, resorting to basic fabrication infrastructure. This work presents the development of a flexible material that exhibits tunable structural color due to its 3D polyethylene based nanonetwork. These nanonetworks are hydrophobic, and change color depending on the refractive index of the material filling their voids. This developed flexible metamaterial is projected to open opportunities for the fabrication of economically affordable (around 0.008 € cm−2) and solvent‐free photonic nanostructures with multipurpose applications such as sensing, energy saving, clothing, and photovoltaics, among others.
