Abstract

Through the observation of the typical plant lotus leaf, rice and nasturtium etc leaf surface wettability, the leaf surface structure of scanning electron microscope, contact angle measurement, self cleaning mechanism of comparative study of typical plant leaf surface structure, clarifying the typical super hydrophobic plant surface wettability difference and its origin. The results showed that the leaf surface of the three kinds of plants had both micro - and nano - surface microstructure, and all of them showed super hydrophobicity. The microscopic morphology is composed of a micron scale mastoid substrate, which is covered with a nano scale waxy fluff, so that the water droplets can not be completely immersed into the substrate and exhibit the super hydrophobic property. The contact angle measurement results prove this point. But unlike the other two is that the super hydrophobic properties of rice leaves are anisotropic, rice leaf surface parallel to the edge of the mastoid leaf direction showed ordered one-dimensional, arbitrary in the vertical direction, water droplets in the rice leaf surface is easy to flow in parallel along the leaf edge direction. The study on the mechanism of wettability of the typical plant leaf surface provides an idea for the development of the surface structure and the preparation of superhydrophobic surface.
