Preparation and characterization of nanoporous alumina membrane made by two-step anodization

摘要

The preparation of different pore diameter and thickness nanoporous alumina membranes by two-step anodic oxidation, and the corrosion resistance and mechanical properties of the alumina membrane were investigated. In order to show the infection of pore diameter and thickness on these properties, the dynamic polarization and nano indentation method were mentioned, at the same time hemolytic test was performed for testing biocompatibility of the membrane.
