Hybrid Topography of Lotus Leaf under Hydrostatic/Hydrodynamic Pressure

Abstract The superhydrophobic characteristics and functional durability of the lotus leaf are determined by its surface flexible multistage topography. In this study, it is found that hybrid arrangement sub‐millimeter (sub‐mm) micron papillae arrays on edge leaves more conducive to resistance hydrostatic hydrodynamic water pressure, which provides a guarantee for survival leaves. Inspired special design, structure prepared template method, whose contains sub‐mm pillars, micropillars, nanostructures. It has obvious advantages in resisting continuous impact droplets. This systematic study reveals why can withstand fluid impact, theoretical experimental basis improving artificial function.
