Advancing in a better understanding of the physics of wetting requires to be able to develop surfaces with well‐controlled roughness by controlling the microstructure morphology. In this study, patterned truncated cones and hierarchical conical structures are fabricated. The wetting properties of the fabricated surfaces are measured for identifying the importance of the geometrical parameters on the wetting states ranging from superhydrophobic to superhydrophilic. In particular, the wetting transition from Cassie–Baxter to Wenzel state and its dependence on the geometrical parameters is investigated. It is observed that the transition is dependent on the center‐to‐center distance and the height of the structures.

分层圆锥形微结构上的润湿状态转变

为了更好地了解润湿的物理原理，需要能够通过控制微观结构形态来形成粗糙度得到很好控制的表面。在这项研究中，图案化的截锥和分层的圆锥形结构被制造。测量制造表面的润湿特性，以识别几何参数对从超疏水到超亲水的润湿状态的重要性。尤其是，研究了从Cassie–Baxter到Wenzel态的润湿转变及其对几何参数的依赖性。可以看出，过渡取决于中心到中心的距离和结构的高度。
