Abstract: A novel super-hydrophobic film was prepared by Livingston solution chemically adsorbed onto the aluminum. A superhydrophobic surface was prepared on aluminum substrate. The film formation and its structure were characterized by means of Fourier transformation infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The formation of a composite interface composed of the flower-like surface nanostructures, water droplet and air trapped in the crevices was suggested to be responsible for the superior water-repellent property. The corrosion behavior of the super-hydrophobic surface was investigated with potentiodynamic polarization measurements and electrochemical impedance spectroscopy. Due to the 'air valleys' and 'capillarity' effects, the corrosion resistance of the material was improved remarkably.
