A facile strategy for the fabrication of a bioinspired hydrophilic–superhydrophobic patterned surface for highly efficient fog-harvesting

The simple lab oven-based thermal pressing of a hydrophilic polystyrene (PS) flat sheet together with a (super)hydrophobically modified metal-based gauze produces a hydrophilic–superhydrophobic patterned surface which exhibits a high fog water collection performance.
