A Hierarchical Anodic Aluminum Oxide Template
Nano Letters, 2020Anodic aluminum oxide (AAO) templates are widely used for the development of various functional nanomaterials due to their highly ordered and tunable porous structures. Here, we report a new hierarchical AAO (hAAO) template with the hexagonally ordered unit cells and the radially distributed nanochannels.

Fabricating Anodic Aluminum Oxide by Anodic-Oxidation
Advanced Materials Research, 2011Uniform parallel pores and controllable pore diameter make Anodic Aluminum Oxide (AAO) membrane one of the best materials in synthesis of one-dimensional nano-structured material. High orderly AAO template was prepared by anodic-oxidation. The prepared AAO membrane’s apertures ranged from 30 nm to 75 nm.

During anodic oxidation of aluminum, the incorporated anion species from the electrolyte are drawn into the growing barrier layer at the pore base by the high electric field and, afterward, migrate inward. The barrier layer consists of acid anion-contaminated regions adjacent to the oxide/electrolyte interface and relatively pure alumina further ...

Controlled self‐cleaning aluminum surfaces mediated by anodic aluminum oxide
Microscopy Research and Technique, 2023AbstractSpecial porous anodic aluminum oxide (AAO) membranes are created on Al in a phosphonic acid electrolyte solution through one‐step anodic oxidation and modified with polydimethysiloxane using a vapor deposition technique. In this context, the anodic oxidation time is tuned during its process.

Conformal Anodic Oxidation of Aluminum Thin Films
Nano Letters, 2005Membrane-based synthesis, also called template synthesis, is a very general approach used to prepare arrays of nanomaterials with monodispersed geometrical features. The most commonly used porous templates are track-etched polycarbonate and porous anodic alumina membranes.

Anodic aluminum oxide microchannel plates
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1998Abstract A new material for microchannel plates (MCP) is proposed – anodic aluminum oxide. Microchannel plates made of this material may be much cheaper than with conventional lead glass MCP. Also a significantly smaller channel diameter (up to 70 nm) is easily achievable, which means better spatial resolution and the possibility to operate in strong

Surface Wettability of Macroporous Anodized Aluminum Oxide
ACS Applied Materials & Interfaces, 2013The correlation between the structural characteristics and the wetting of anodized aluminum oxide (AAO) surfaces with large pore sizes (>100 nm) is discussed. The roughness-induced wettability is systematically examined for oxide films grown by a two-step, high-field anodization in phosphoric acid of three different concentrations using a commercial ...

Structure of Anodic Oxide Coatings on Aluminum
Angewandte Chemie, 1989Communication: The structure of the remarkably uniform array of pores in surface coatings on aluminum has been investigated using X‐ray and neutron diffraction techniques. The almost hexagonally shaped cells make the films of interest for application in the field of synthetic membranes and as supports for active materials.
