Abstract

A sponge-like cotton fabric autonomously collects and releases water from fogs triggered by typical day-and-night temperature variations. The reversible switching between absorbing-superhydrophilic/releasing-superhydrophobic states results from structural changes of a temperature-responsive polymer grafted on the very rough fabric-surface. This material and concept presents a breakthrough into simple and versatile solutions for collection, uni-directional flow, and purification of water captured from the atmosphere.
