Abstract: Both superhydrophilic and superhydrophobic surfaces have great application value in many fields. In this article, anodized aluminum oxide (AAO) membranes prepared by two-step high-field anodizing were subjected to wet chemical etching and high-temperature annealing. The change of surface wettability characteristics with post-treatment conditions was studied. The results showed that, with the increase of etching duration, the water contact angle (WCA) of AAO membranes increased first and then decreased to a minimum fixed value. As the etching duration was more than 90 min, the etched AAO membranes showed superhydrophilic characteristic (WCA<10°). The WCA of AAO membranes etched at different time with high temperature annealing was larger than that without high temperature annealing, and the WCA increased with the increase of etching time. Especially when the etching time was 120—180 min, the AAO membranes were superhydrophobic and highly viscous. while the AAO membranes with etching time of 200 min showed extremely low superhydrophobic characteristic (WCA>150°) and ultralow viscosity, and the average contact duration between the AAO membranes surface and droplet was only 4.6 ms. The as-prepared superhydrophobic AAO membranes were of good time stability. Also the mechanism of the wettability of AAO membrane changing with post-treatment conditions was analyzed. The results obtained in this article provide a new idea for design functional solid surfaces with different wettability and have good practical application value.
