    Ultrathin AAO templates have self-organized honeycomb-like nanopores, and they are usually from several ten nanometers to several hundred nanometers in thickness.Ultrathin AAO templates have been widely used for fabrication of large-scale ordered arrays of surface nanostructures such as nanodots and nanoholes on the surface of substrates. Pores of ultrathin AAO template are uniform in diameter and highly ordered in a short-range. In addition, the material (Al2O3) is transparent in the near-infrared and visible spectrum, and is electrically insulated. Compared to other technology for making ord...

    AAO on Al substrate has honeycomb-like structure (shown in Fig. 1), composed with hexagon column of Al2O3, with a circular pore in the center. At the end of the pore, there is a half-sphere shape barrier layer oxide layer in contact with aluminum. The porous oxide film contains mutually parallel cylindrical pores extending from the barrier oxide layer to the film surface. AAO on Al substrate is the simplest product in AAO family, which can be fabricated into large area with a high success rate. Fig. 2 shows a typical picture of the AAO template.Fig. 1. Schematic of AAO on Al substrate.  F...

    Isotropic AAO templates, often referring to thicker AAO to be different from ultrathin AAO membrane, are widely used for a number of different fields. Topmembranes technology is specialized to make high quality isotropic AAO templates, with highly uniform and regular pore on both sides of the surfaces. The pores are arranged hexagonally within the single grains of the aluminum. The translucent nature of AAO is appealing to applications in biomedical field.Fig. 1. The structure diagram of isotropic AAO templates.Fig. 2. Typical SEM images of both sides of isotropic AAO template. Fig. 3. Ty...

V shape AAO on substrate

Author: 76

A new type of AAO product (V-shape AAO) is developed by Topmembranes Technology. Compared to other anodic alumina membranes products, this profile of type of AAO is precisely tailored by the synergistic control of anodizing time, etching time and cyclic times, resulting in a unique structure for a wide range of applications.


For more applications of V-shape AAO, please refer to: Adv. Mater. 2014, 26, 2805;ACS Nano, 2015, 9, 10287;Adv. Funct. Mater. 2017, 27, 1604720;Nanoscale Research Letters 2013, 8,268;J. Phys. Chem. C 2017, 121, 9757; Nano Energy, 2016, 22, 539; ACS Nano 2017, 11, 5113.

V shape AAO template is a special AAO template with taper-nanopore or inverse-nanocone, which is similar with AAO on aluminum substrate. The schematic is shown in Figure 1. From the cross-section SEM images, we can clearly tell the profile is an inverse-core or V shape, with larger pore diameter at the top gradually decreasing into smaller diameter at the bottom.  Like AAO on Al substrate, there is a barrier layer at the bottom followed by the non-anodized aluminum substrate.

Currently, Topmembranes Technology produced two types of V-shape AAO templates.

V-shape AAO template has a highly efficient porous structure on the front surface. The front surface is facing to the logo side, as shown in Figure 4. Such AAO template has support structure on the bottom, therefore it is very strong and can be bent slightly. Ultrasound cleaning is also ok (a few minutes). Please do avoid touching the surface with bare hand.
