“…[7][8][9] For an ideal interfacial SSG system, photothermal evaporators usually consider three main factors, including efficient photothermal conversion, excellent heat management, and adequate water transport. [10][11][12][13][14][15][16] Extensive efforts have been devoted to increasing the evaporation rate and photo-to-heat conversion efficiency of SSG systems by employing materials including porous membranes, [17][18][19][20] fabrics, [21][22][23][24] wood scaffolds, 25,26 foam frameworks, [27][28][29] and hydrogel composites. [30][31][32][33] Compared to other reported evaporators, hydrogel-based evaporators present appealing salt resistance and water purication performance, attributed to their intriguing abilities to achieve thermal localization, water activation, and self-oating.…”
