Abstract Direct solar desalination exhibits considerable potential for alleviating the global freshwater crisis. However, prevention of salt accumulation while maintaining high water production remains an important challenge that limits its practical applications because methods currently employed achieving rapid backflow usually result in heat loss. Herein, we fabricate a evaporator featuring vertically aligned mass transfer bridges transport and backflow. The 3D open architecture constructed using enables to efficiently utilize conductive would otherwise be lost, significantly improving evaporation efficiency without compromising on rejection. fabricated can treat with more than 10% salinity. Moreover, it continuously steadily work real environment under natural sunlight solar-to-water collection >40%. Using discharged from reverse osmosis plants sea Red Sea, demonstrates daily generation rate ~5 L/m 2 , which is sufficient satisfy individual drinking requirements. With strong rejection, energy efficiency, simple scalability, has promise supply water-stressed off-grid communities.

Solar evaporation is one of the most attractive and sustainable approaches to address worldwide freshwater scarcity. Unfortunately, it still a crucial challenge that needs be confronted when solar evaporator faces harsh application environments. Herein, promising polymer molding method combines melt blending compression molding, namely micro extrusion proposed for cost-effective fabrication lightweight polyethylene/graphene nanosheets (PE/GNs) foam with interconnected vapor escape channels surface micro-nanostructures. A contact angle 155 ± 2°, rolling 5 1° reflectance ≈1.6% in wavelength range 300-2500 nm appears on micro-nanostructured PE/GNs surface. More interestingly, can maintain robust superhydrophobic state under dynamic impacting, high temperature acid-/alkali solutions. These results mean possesses self-cleaning, anti-icing photothermal deicing properties at same time. Importantly, exhibits an rate 1.83 kg m-2 h-1 1 Sun illumination excellent salt rejecting performance used as self-floating evaporator. The provides ideal industrialized approach mass production evaporators suitable practical
