Novel Fabrication of Nanoporous Alumina Membrane Microtubes: 2-Dimensional Nanoporous Arrays on Every Facets of Microtubes

摘要

Free-standing nanoporous alumina membrane microtubes with different shapes (rectangular and cylindrical tubes) and variable dimensions were easily fabricated by direct anodization of the aluminum templates of the specified shapes (strip and wire) and dimensions during the electrochemical reaction.
