Abstract

This work describes the investigation of the physical basis of the amazing water repellence of some plant leaves, which is in addition to self-cleaning properties known as the "Lotus effect". Two rather different possible mechanisms are proposed, which are suggested to cover the main physics in a majority of superhydrophobic systems. These concepts are illustrated with two different types of plant leaves as well as a model surface carrying carbon nanotube aggregates.

摘要

这项工作描述了对一些植物叶片惊人疏水性物理基础的研究，这种疏水性除了具有被称为“荷叶效应”的自清洁特性外。提出了两种截然不同的可能机制，它们被认为涵盖了大多数超疏水系统中的主要物理原理。用两种不同类型的植物叶片以及一个带有碳纳米管聚集体的模型表面对这些概念进行了说明。
