Water harvesting method via a hybrid superwettable coating with superhydrophobic and superhydrophilic nanoparticles
TL;DR: In this paper, a new biomimetic method, inspired by the fog harvesting ability of hydrophobic-hydrophilic surfaces of Namib desert beetles, is presented, which envisages a low-cost preparation (by the photocatalysis of titanium dioxide through ultraviolet irradiation) of a titanium dioxide-silicon dioxide hybrid superwettable surface combining superhydrophobic and super hydrophilic nanoparticles and exhibiting excellent water/fog collection properties.
