a Schematic illustration of the fabrication procedure of bilayer-structured evaporator, where porous PDA photothermal layer was fabricated via in-situ polymerization and following by a facile dip-coating process, the thermo-responsive sporopollenin layer was assembled on the bottom skeleton of NiF foam. SEM images of p-PDA coating layer. b The porous structure of foam skeleton. c p-PDA nanospheres, SEM images of water transport gating layer d The skeleton decorated with PNm-g-SEC microparticles. e The interaction between PNm-g-SEC microparticles and PDA layer.
