나노 표면 구리 관의 물 수집 성능

Water harvesting from humid air is an available solution for solving water shortage problem. In this researches, the pinning pressure between a surface and droplet is critical factor for the amount of harvested water. Herein by using the contact line force analysis, we show the wetting properties and geometry effect are related with the pinning force. And as measuring mass and falling frequency on various nano/micro engineered surfaces, we experimently reported harvesting dynamics by two effects and suggested optimal surface for harvesting water. The super-hydrophilic surface are found to have best performance and the geometry effect is found to change the droplets mobility.
