Isotropic AAO templates

Date: 2018-03-13
Author: network

AAO on Al substrate has honeycomb-like structure, 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. So AAO on Al substrate is suitable to fabricate polymer nanowires or nanotubes.


Fabrication of polymer nanowires or nanotubes

Isotropic AAO templates

Fabrication of polymer nanowires or nanotubes by (a) heat- and pressure-driven nanoimprint and (b) polymer solution and pore wetting.
