In this Article, superhydrophobic CuO surfaces with different topographies have been fabricated by combining both a simple solution-immersion process and self-assembly of fluoroalkylsilane. We regulate the solution-immersion process by changing the immersion time, the growing temperature, and the solution compositions to control different topographies of CuO surfaces. The as-prepared superhydrophobic surfaces possess tunable water adhesion that ranges from extremely low to very high, on which the sliding angle is 3 卤 1, 12 卤 1, 28 卤 2, 39 卤 2, and 90掳 (the water droplet is firmly pinned on the superhydrophobic surface without any movement at any tilted angles), respectively. Our work provides a facile and promising strategy to fabricate superhydrophobic surfaces with tunable adhesion.
