On June 22, a collaborative team from the Institute of Process Engineering at the Chinese Academy of Sciences and Shenzhen University introduced a polymer "lock" mechanism. This innovative approach successfully incorporates nanoparticles into a three-dimensional photothermal evaporation material, substantially accelerating the rate of solar-powered seawater evaporation. The relevant research findings have been published in an international academic journal. Experiments demonstrate that, through multiple scattering and absorption processes, the structure achieves an impressive solar light absorption rate of up to 90.2%. Concurrently, the nano-confined space modifies the hydrogen bonding network between water molecules, thereby reducing the energy required for the evaporation of an equivalent amount of water by 45.7%. In testing, a single evaporator attained an evaporation rate of 38,100 grams per square meter per hour, which is 8.5 times higher than that of the two-dimensional film previously developed by the team. Furthermore, during a 30-day accelerated seawater aging test, the material exhibited no nanoparticle shedding and did not produce reactive free radicals under light exposure, effectively addressing the challenge of organic substrate degradation. Currently, the research team is concentrating on enhancing condensation efficiency and lowering system costs to facilitate the widespread adoption of this technology in coastal regions facing water scarcity, islands, and remote areas. Their aim is to realize the early conversion of sunlight and seawater into safe, drinkable freshwater.
