Abstract

Salsola crassa plant hairs collect fog in their natural arid climate habitat through the capture and growth of water droplets. These then, either drip onto the ground below due to gravity, or coalesce into larger attached water droplets, whilst concurrently rolling downwards along the curvature of the Salsola crassa leaf (fog collection and water channelling mechanism). Non-woven and cotton fibrous materials are shown to mimic the fog harvesting behaviour of Salsola crassa hairs, where the overall mist collection efficiency can be enhanced by over 300 percent through the incorporation of multiple length scale (hierarchical) channel structures in conjunction with hydrophobic surface functionalisation.
