Abstract

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.
