A　Cu2O　layer　was　employed　as　a　new　method　to　achieve　the　superhydrophobicity　on　a　copper　Surface　using　a　simple　hydrothermal　method.　First,　a　Cu2O　layer　With　a　hierarchical　structure　was　grown　on　the　copper　surface　using　at　oxidization　step　and　it　exhibited-the　hydrophilicity.　The　analysis　results　of　XRD　and　XPS　confirmed　the　formation　of　a　Cu2O　phase　on　the　copper　surface.　Second,　the　Cu-O(2)　surface　was　changed　to　superhydrophobicity　via　a　modifying　process　using　1H,1H,2H,2H-perfluorodecyltriethoxysilane,　Peaks　corresponding　to　F1s,　-CH2,　-CF2　and　-CF3　groups　in　the　XPS　spectra　confirm　the　assemblage　of　the　F-contained　radicals　on　the　surface.　The　wetting　mechanism　is　discussed　briefly.　Wetting　tests　also　demonstrate　that　a　water　droplet　on　the　can　slide　away　very　easily,　I　even　with　only　a　slight　tilt　and　that　it　has　a　lower　adhesion　to　the　modified　surface.
