Researchers at the Institute of Process Engineering, Chinese Academy of Sciences, with Shenzhen University developed a polymer "latch" mechanism to assemble nanoparticles into a three-dimensional photothermal evaporator that sharply raises solar-driven seawater evaporation. The structure achieves 90.2% solar absorption; nanoscale confinement alters the water hydrogen-bond network and cuts the energy required for the same evaporation volume by 45.7%. A single evaporator recorded an evaporation rate of 38.1 kg/hr per m2, 8.5x the team’s prior 2D films. In a 30-day accelerated seawater aging test there was no nanoparticle shedding; the material produced no photo-induced reactive free radicals and addressed organic-substrate degradation. Results published in Advanced Materials. The team is working to improve condensation efficiency and reduce system costs to enable scale-up for coastal water-scarce regions, islands and remote agricultural irrigation.
