通过制作不同的图案，包括网状，球形仙人掌状，和倾斜的纳米棒结构，实现了对超疏水MnO（2）纳米结构膜上的粘附力的调节。从130到近0 μN的粘附力的奇妙调制范围赋予这些超疏水表面非常不同的水滴动力学特性。这种依赖于图案的粘合性质归因于由三界面接触线的不同连续性导致的动力学势垒差异。这一发现将为超疏水表面的粘附调节提供一般策略。
Tuning the adhesive force on a superhydrophobic MnO(2) nanostructured film was achieved by fabricating different patterns including meshlike, ball cactus-like, and tilted nanorod structures. The marvelous modulation range of the adhesive forces from 130 to nearly 0 μN endows these superhydrophobic surfaces with extraordinarily different dynamic properties of water droplets. This pattern-dependent adhesive property is attributed to the kinetic barrier difference resulting from the different continuity of the three-interface contact line. This finding will provide the general strategies for the adhesion adjustment on superhydrophobic surfaces.
