The　research　of　superhydrophobic　materials　has　attracted　many　researchers＇　attention　due　to　its　application　value　and　prospects.　In　order　to　expand　the　serviceable　range,　people　have　investigated　various　superhydrophobic　materials.　The　simple　and　easy　preparation　method　has　become　the　focus　for　superhydrophobic　materials.　In　this　paper,　we　present　a　program　for　preparing　a　rough　surface　on　an　aluminum　foil,　which　possesses　excellent　hydrophobic　properties　after　the　treatment　with　low　surface　energy　materials　at　high　vacuum.　The　resulting　contact　angle　is　larger　than　160　degrees,　and　the　droplet　cannot　freeze　on　the　surface　above　10　degrees　C.　Meanwhile,　the　modified　aluminum　foil　with　the　thickness　of　less　than　100　mu　m　can　be　used　as　an　ideal　flexible　applied　material　for　superhydrophobicity/anti-icing.
