Solar water evaporation with a leaf-like microstructured graphene/poly(N-isopropylacrylamide) (mG/PNIPAm) membrane is described by L. Qu and co-workers in their Communication on page 16343 ff. In response to varying sunlight intensities, the water evaporation rate of this leaf-like mG/PNIPAm membrane is tuned through opening and closing of the water transport channels in a process reminiscent of the stomatal opening and closing of leaves. A double-layer membrane variant can further tailor water loss through self-curling.
