NOVELTY - Preparing super-hydrophobic aluminum alloy comprises placing an aluminum alloy sheet in an electro-deposited metal nickel precursor, adding hydrophobic material in electro-deposition process, applying direct current to the aluminum alloy sheet to form a composite layer of metal oxide on the aluminum alloy sheet, placing the aluminum alloy sheet in a mixed solution containing graphene oxide, polymer with amino or hydroxy and reducing agent, reducing the graphene oxide and drying to obtain an aluminum alloy modified by a three-dimensional network-shaped composite surface. USE - The alloy is useful in self-cleaning, corrosion resistant, freezing and electrocatalysis hydrogen evolution. ADVANTAGE - The alloy has good self-cleaning property, corrosion resistance and anti-freezing property.
