Technologies　for　evaporation-driven　electricity　generation　and　solar-driven　steam　generation　exhibit　significant　potential　for　addressing　energy　crises　and　freshwater　shortages.　Nevertheless,　it　is　still　a　challenge　to　develop　multifunctional　materials　for　efficient　energy　generation　and　seawater　desalination　via　economical　and　simple　methods.　Here,　we　propose　a　Chinese　ink-coated　viscose　fiber　composite　(Ink@VF),　suitable　for　direct　applications　in　evaporation-driven　electricity　generators　(EEGs)　and　solar-driven　steam　generators　(SSGs).　The　Ink@VF　prepared　by　a　simple　dip-dyeing　method　exhibits　excellent　mechanical　properties　(Young’s　modulus　of　18.1　GPa),　hydrophilicity,　electrical　conductivity　(36.51　Ω/sq),　and　photothermal　conversion　properties.　Based　on　the　synergy　of　water　evaporation,　capillary　effect,　and　electric　double　layer　(EDL)　electrokinetic　effect,　the　Ink@VF-based　EEG　can　achieve　a　maximum　open-circuit　voltage　(Voc)　of　0.65　V　and　an　optimal　power　density　of　43.72　mW/m2　with　1　mol/L　NaCl　solution.　It　can　also　be　integrated　in　series　to　develop　a　self-powered　bracelet.　Simultaneously,　the　evaporation　rate　and　solar　energy　conversion　efficiency　of　the　Ink@VF-based　SSG　can　reach　1.32　kg/(m2·h)　and　84.9%　under　1　sun　irradiation,　respectively.　Through　utilizing　the　evaporation-condensation　mechanism,　it　can　achieve　freshwater　generation　at　a　rate　of　1.49　kg/(m2·h)　and　metal　ion　removal　in　excess　of　99.9%.　This　study　provides　a　low-cost　and　efficient　solution　to　the　energy　crisis　and　freshwater　shortage　in　resource-poor　remote　areas　by　utilizing　inexhaustible　natural　resources.　©　2025,　Tsinghua　University　Press.　All　rights　reserved.
