Abstract
A facile approach is presented in this paper on fabricating a special surface whose wettability can switch reversibly between superhydrophobicty and superhydrophilicity. The approach includes anodic oxidation, gold layer spraying and thiols modification. After modified by the mixed thiol solution, the contact angle of the surface transits sharply from about 160
