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.
