Figure 4. Time-lapse images of the fog harvesting on K.Oil 5cst, S.Oil 5cst, S.Oil 100cst, S.Oil 1000cst, and S.Oil 1000cst surfaces.

Contrary to the SHPo surface, the droplet shedding dynamics is not influenced by the high super-saturation condition due to the presence of a thin lubricant layer covering nanostructures, as manifested by the identical contact angles under the general condition and high super-saturation condition.
