Abstract:Hydrogel solar evaporators are emerging as a promising platform for solar-powered water purification. However, developing durable and highly efficient light-absorbing hydrogels remains challenging due to inevitable salt accumulation during desalination, difficulties in controlling surface topography, and poor mechanical properties of the hydrogel evaporator. This study employed a simple foam polymerization strategy to fabricate a sponge-like hydrogel with a three-dimensional interconnected porous structure. Ad… Show more
