Abstract
AbstractInterfacial solar steam generators (ISSGs) can capture solar energy and concentrate the heat at the gas–liquid interface, resulting in efficient water evaporation. However, traditional ISSGs have limitations in long‐term seawater desalination processes, such as limited light absorption area, slow water transport speed, severe surface salt accumulation, and weak mechanical performance. Inspired by lotus seedpods, a novel ISSG (rGO‐SA‐PSF) is developed by treating a 3D warp‐knitted spacer fabric with plasma (PSF) and combining it with sodium alginate (SA) and reduces graphene oxide (rGO). The rGO‐SA‐PSF utilizes a core‐suction effect to achieve rapid water pumping and employs aerogel to encapsulate the plasma‐treated spacer yarns to create the lotus seedpod‐inspired hydrophilic stems, innovatively constructing multiple directional water transport channels. Simultaneously, the large holes of rGO‐SA‐PSF on the upper layer form lotus seedpod‐inspired head concave holes, enabling efficient light capture. Under 1 kW m−2 illumination, rGO‐SA‐PSF exhibits a rapid evaporation rate of 1.85 kg m−2 h−1, with an efficiency of 96.4%. Additionally, it shows superior salt tolerance (with no salt accumulation during continuous evaporation for 10 h in 10% brine) and self‐desalination performance during long‐term seawater desalination processes. This biomimetic ISSG offers a promising solution for efficient and stable seawater desalination and wastewater purification.
