(A) cleaning the surface of the aluminum material; And (b) forming a metal oxide layer on a surface of the aluminum material cleaned in the step (a). The present invention also provides a method for modifying the chemical surface of aluminum for improving corrosion resistance. Further, after a metal oxide layer is formed on the surface of the aluminum material, 1H, 1H, 2H, 2H-perfluorodecyl trimethoxysilane (1H, 1H, 2H, 2H-Perfluorodecyltrimethoxysilane) and Toluene-containing mixed solution to form a superhydrophobic surface on the aluminum material. According to the chemical surface modification method of aluminum for improving corrosion resistance according to the present invention, a chemical surface modification technique for forming a metal oxide layer on the surface of an aluminum material and a surface energy reduction technique for forming a super water- A greatly improved aluminum material can be manufactured. |
