WETTED STRUCTURE, LIQUID MOVEMENT CONTROL STRUCTURE AND METHOD OF LIQUID MOVEMENT CONTROL

摘要

Liquid evaporation is carried out while controlling liquid position and movement on a wetted surface on the basis of a difference of surface area multiplication factor by a convex structure provided on the wetted surface. Wetted structure (1) has lyophilic surface (2) provided with multiple convex structures (3) and brought into contact with given liquid. The lyophilicity of the surface (2) differs depending on region of the surface (2) in accordance with a difference of surface area multiplication factor attributed to the convex structures (3), and the surface (2) is so constructed that the lyophilicity is maximized inside given region (4) provided on the surface (2).
