| Resumo: | [EN] This project focuses on the design and characterization of anodic porous alumina (APA), also known as anodic aluminum oxide (AAO), templates, manufactured through electrochemical conversion of aluminum foil. The goal was to investigate the influence of anodization and pore-widening parameters on the morphology of the resulting templates, and therefore, to evaluate their suitability for subsequent electrodeposition applications. Anodizations were mainly performed in a 0.3 M oxalic acid electrolyte, under different voltages, temperatures, anodization times and stirring conditions. Moreover, one comparative anodization was carried out in phosphoric acid, to obtain larger pores. After the anodization, selected samples underwent pore-widening treatments in phosphoric acid, with controlled durations, in order to adjust their pore diameters. The structural properties of the templates, such as pore diameter, interpore distance and oxide layer thickness (pore height), were characterized using scanning electron microscopy (SEM). Finally, preliminary copper electrodeposition trials were conducted, using a 0.1 CuSO₄ solution, to assess the ability of the designed templates to support metal deposition, within the porous structure. Deposition conditions were estimated based on Faraday’s law. These trials provided an initial evaluation of the relationship between template morphology and electrodeposition behavior. Overall, this study shows that APA templates characteristics can be tuned by controlling anodization and pore-widening conditions, which highlights their potential for electrodeposition-based nanostructuring applications. |
