More than 400 million years of evolution of land plants led to a high diversity of adapted surface structures. Superhydrophobic biological surfaces are of special interest for the development of biomimetic materials for self-cleaning, drag reduction, and energy conservation. The key innovation in superhydrophobic biological surfaces is hierarchical sculpturing. In plants, a hydrophobic wax coating creates water-repelling surfaces that in combination with two or more levels of sculpturing leads to superhydrophobicity. Hierarchical structuring is of special interest for technical "biomimetic" materials with low adhesion and self-cleaning properties. Here we introduce hierarchical surface sculptures of plants with up to six levels. The article gives an overview of the composition of hierarchical surfaces for superhydrophobicity and their use as models for the development of artificial self-cleaning or drag-reducing surfaces.
陆地植物经过超过 4 亿年的进化，形成了高度多样化的适应表面结构。超疏水生物表面对于开发用于自清洁、减阻和节能的仿生材料具有特殊的意义。超疏水生物表面的关键创新是分级微造型。在植物中，疏水性蜡涂层形成拒水表面，与两个或更多层次的微造型相结合，导致超疏水性。分级结构对于具有低附着力和自清洁特性的技术“仿生”材料特别有意义。在这里，我们介绍了具有多达六个层次的植物分级表面雕塑。本文概述了超疏水的分级表面的组成及其作为开发人工自清洁或减阻表面的模型的用途。
