The Al 3104 alloy is commonly utilized in the industrial field for building exteriors, heat blockers, and aluminum cans, but often exposed to long-term pollution leading to economic loss. In order to address this issue, researchers have actively studied self-cleaning of metal surfaces by modifying surface structures, including various nanostructures to control wettability.
The Al 3104 alloy is widely used in the industrial field for building exteriors, heat blockers, and aluminum cans. These products are often exposed to long-term pollution, resulting in economic loss due to corrosion and the removal of pollutants. To solve these problems, self-cleaning of metal surfaces has been actively studied. Selfcleaning can be achieved by modifying hydrophilic or hydrophobic treatments to control the surface energy and surface structure. In the present study, the surface structure was changed through anodization technique. We fabricated three different structures of the top surface: nanotubes, porous, and nanopetals. The various nanostructures exhibited differences in wettability. Under the optimum conditions, the aluminum oxide layer exhibited hydrophilicity, which is a significant advantage for self-cleaning.
