Super-Hydrophobic Film Prepared with Reduced Graphene Sheets and its Application as Corrosion Barrier to Copper

Abstract:

Electrophoretic deposition is proposed to fabricate super-hydrophobic film on copper surface with reduced graphene sheets (RGSs). The resulted film was characterized with contact angle meter, scanning electron microscopy and so on. It is found that the film presents super-hydrophobic property with water contact angle of 150.4°. Air can be trapped in the island-like structure and intensify the wettability of film. Electrochemical measurements prove that super-hydrophobic film can inhibit corrosion process of underlying copper by inducing both anodic and cathodic current density. This method for super-hydrophobic film fabrication is facial and time-saving, and it will expand the application of RGSs in mechanical engineering.
