METHOD FOR MANUFACTURING ALUMINUM ALLOY ANODIZED FILM HAVING SUPERHYDROPHOBIC SURFACE

摘要

The present invention relates to a method for manufacturing an aluminum alloy anodized film having a superhydrophobic surface and an aluminum alloy having an anodized film with a superhydrophobic surface manufactured by the method. The present invention has an economical effect that an aluminum alloy, in which a three-dimensional shaped anodized film structure formed on the surface thereof is controlled in various forms, such as a pillar-on-pore structure, may be manufactured at low costs within a short time. The aluminum alloy with the controlled anodized film structure has excellent superhydrophobicity, corrosion resistance, and thermal conductivity, and thus may be used in various industrial fields, such as electronic device housings, LED lighting covers, heat exchangers, pipes, road structures, automobiles, aircrafts, ships, and generators.
