Special porous anodic aluminum oxide (AAO) membranes are created on Al in a phosphonic acid electrolyte solution through one-step anodic oxidation and modified with polydimethysiloxane using a vapor deposition technique. In this context, the anodic oxidation time is tuned during its process. As such, the Al surface's wettability, and self-cleaning property are controlled by the tunable anodic oxidation time, for the anodic oxidation, time can regulate the structure of the AAO and the proportion of the air-liquid interface.
Keywords: Al2O3; anodic oxidation; controlled self-cleaning; superhydrophobic; vapor deposition.
