ABSTRACT Solar‐driven seawater desalination is considered an promising technology coping with water scarcity due to the sustainability of solar energy and its substitutability for fossil fuels. Nevertheless, complex fabrication, high cost low efficiency solar‐driven evaporator limit large‐scale application. Herein, PDA/PU composite foam porous three‐dimensional structure developed achieve high‐efficient evaporation. Thereinto, hydrophilic PDA contributes real absorption, provides extremely photothermal conversion efficiency. Meanwhile, PU excellent capillary effect sufficient supply. The as‐fabricated can reach 77.8°C 48.1°C under laser simulated irradiation (1 kW/m 2 ), respectively. Further, specific evaporation rate 1.93 kg/m h −1 irradiation. Therefore, exhibits effective which inspiration future development high‐performance devices.
