The characteristics of water-evaporation from a glassy carbon (GC) plate with nano-structure surface were investigated. The nano-scale structures on the carbon plate are made by Oxygen ion beam process. In changing the exposure time in the Ion beam process, it can be changed as for the pitch and diameter of nano-structure with conical structures. The experiment measured the temperature of GC plate and weight of a water-droplet while the droplet evaporates on the heating carbon plate. Consequently, special evaporation appeared when the pitch of nano-structure with the conical structures was larger than 80 nm.
