| Outline of Final Research Achievements |
We have tried to understand wetting phenomena on the surfaces of living matter such as plants, insects and animals from the viewpoints of static wetting and dynamic wetting. Actually, we have observed penetration of a water droplet into a hydrophobic cylindrical pore, rolling water droplets on lotus leaf, bouncing phenomena of water droplets on lotus leaf, and so on. To understand these phenomena, we found that several factors are essentially important. The factors are surface energy and interfacial energy of a water droplet, potential energy of a water droplet, pinning energy applied to a water droplet due to surface structure, energy dissipation due to viscosity in a water droplet, Laplace pressure due to surface structures and dynamic pressure generated by the impact of a water against a substrate. The semi-quantitative discussion based on the comparison between these factors allows us to understand the wetting phenomena on the surfaces of plants, insects and animals.
