Temperature-Triggered Collection and Release of Water from Fogs by a Sponge-Like Cotton Fabric (Adv. Mater. 8/2013)

A sponge‐like cotton fabric autonomously collects and releases water from fogs, triggered by day‐ and night temperature variations, typically encountered in dry areas. The reversible switching between absorbing‐superhydrophilic/releasing‐superhydrophobic states results from structural changes of a t...

Zusammenfassung:A sponge‐like cotton fabric autonomously collects and releases water from fogs, triggered by day‐ and night temperature variations, typically encountered in dry areas. The reversible switching between absorbing‐superhydrophilic/releasing‐superhydrophobic states results from structural changes of a temperature‐responsive polymer grafted on the highly rough fabric‐surface, as reported by John H. Xin, A. Catarina C. Esteves and co‐workers on page 1150. This breakthough may help to reduce water depletion in dry areas.
