The anodic oxidation of aluminium is an electrochemical technique that allows obtaining nanostructures with easily adjustable morphology depending on the synthesis variables, for its application in medicine, engineering, biotechnology, electronics, etc. In this work, low-cost alu-minium oxide nanostructured films were synthesized and morphologically characterized using two anodization steps in sulphuric acid, varying the concentration and temperature of the electrolyte and anodization voltage. The order of the porous matrix, pore diameter, interpore distance, pore density, thickness, and porosity were measured and statistically analyzed. The results showed that under the proposed conditions it is possible to synthesize low-cost nanoporous aluminium oxide films, with a short-range ordering, being the best ordering conditions 10 ◦C and 0.3 M sulphuric acid at 20 V and 5 ◦C and 2 M sulphuric acid at 15 V. Furthermore, it was determined that the pore diameter and the interpore distance vary proportionally with the voltage, that the pore density decreases with the voltage and increases with the concentration of the electrolyte, and that the thickness of the oxide film increases with electrolyte concentration, temperature, and anodization voltage. 2021-03-09 info:eu-repo/semantics/article info:ar-repo/semantics/artículo info:eu-repo/semantics/publishedVersion https://hdl.handle.net/20.500.12219/5022 eng info:eu-repo/semantics/altIdentifier/doi/https://doi.org/10.3390/coatings11030309 info:eu-repo/semantics/altIdentifier/hdl/https://ri.conicet.gov.ar/handle/11336/170532 info:eu-repo/semantics/altIdentifier/urn/https://www.mdpi.com/2079-6412/11/3/309#cite info:eu-repo/semantics/openAccess application/pdf application/pdf 4 MB MDPI AG
