Aims: Since the 19th century, there has been considerable research effort in
the fabrication, and characterization of nanoporous materials. These nanoporous materials
are highly scientifically and technologically relevant as a result of the surface openings
that have controllable dimensions at both the micrometer and nanometer scales.
Nanoporous alumina foil has been a template of choice in various applications due to its
simplicity and ease of fabrication.
Purpose: The purpose of this review is to provide an insight into the aluminum anodization
steps and the different types of electrolytes that have been used to fabricate
nanoporous alumina template.
Results: In this paper we also briefly review the developments in the anodization of
aluminum foil in relation to its mechanical properties, and the various ordered and disordered
nano pores that are likely to be obtained from the surface morphology.
Keywords: Anodic aluminum oxide, anodization, barrier oxide, electrolytes, nanoporous, mechanical
