Schematic images of water droplet growth and aggregation model, which is the mechanism for the formation of liquid water in a hydrophobic pore structure. (Step 1) Liquid water droplets less than 1 µm in diameter condense at locations in the hydrophobic porous material. (Step 2) The water droplets grow with a spherical shape. If there are water droplets nearby, then they possibly coalesce when they come into contact with each other. (Step 3) The spherical shape of the liquid water droplets is stable, and the droplets surround hydrophobic material. |
