Condensation of Water on Superamphiphobic Surfaces

C03 addresses the wetting behavior of condensate droplets on superhydrophobic and superamphiphobic surfaces with the aim of making this process extremely effective, efficient and resistant.

How is the wetting behavior of condensate droplets on superhydrophobic and superamphiphobic surfaces?

To achieve this goal, individual droplets first should be generated inside the surface structure and the interfacial energy released upon droplet coalescence must be sufficient for forcing the droplets to jump onto the surface and roll off. There is a strong link to the generic drop configuration in A02. Confocal microscopy with high resolution is used, and adhesion forces are measured in order to correlate with microscopic wetting processes. The method could, e.g., become very important to freshwater generation from fog or desalination of seawater.
