Environmental pollution and sewage surges necessitate effective water purification methods. Solar interfacial evaporation offers a promising solution, which needs advancements in salt resistance, efficiency, stability. Herein, inspired by the structure of wood, unidirectional freeze-drying method was used to develop vertically aligned channels antioil-fouling poly(vinyl alcohol)-CNTs-waste carton fiber@polydopamine (PVA-CNTs-WCF@PDA) aerogel for desalination wastewater treatment. The anisotropic three-dimensional porous enables it rapidly transport interface resist deposition. Meanwhile, its unique is combined with CNTs PDAs excellent broadband spectral absorption capacity because composite aerogels can interact molecules reduce their vaporization enthalpy. shows an photothermal rate (2.626 kg m-2 h-1) efficiency (94.24%) under one-sun irradiation. Additionally, evaporator conduct 10 consecutive evaporations 3.5% brine, indicating that has ability desalination. Finally, also purify oil-in-water emulsion mine wastewater.
