Formation of aluminum oxide nanostructures via anodization of Al3104 alloy and their wettability behavior for self-cleaning application

摘要: Abstract 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 economic loss due corrosion removal of pollutants. To solve these problems, self-cleaning metal surfaces has been actively studied. Self-cleaning can be achieved by modifying hydrophilic or hydrophobic treatments control surface energy structure. In present study, structure was changed through anodization technique. We fabricated three different structures top surface: nanotubes, porous, nanopetals. various nanostructures exhibited differences wettability. Under optimum conditions, oxide layer hydrophilicity, which a significant advantage self-cleaning.
