The synthesis of biomimetic, micro­patterned surface coatings with topographical and chemical features to capture water from a humid atmosphere is demonstrated. The coatings are prepared by dewetting thin polymer films to create materials consisting of raised hydrophilic bumps on a hydrophobic background. An enhanced rate of water condensation is measured on these surfaces under representative climatic conditions.
