英文摘要	Solar-driven interfacial evaporation is a green and efficient technology with wide applications, such as seawater desalination, wastewater treatment and electrical generation, and so on. Herein, we report a novel composite aerogel (PI-MWCNT-MHGM) using (3-aminopropyl)triethoxysilane modified hollow glass microspheres (MHGM), carboxylated multiwalled carbon nanotubes (MWCNT), and water-soluble polyamide via simple directional freezing and freeze-drying methods for solar-driven interfacial evaporation. Owing to the directional freezing method, the hollow structure of HGM, and strong chemical interactions in PI-MWCNT-MHGM, the PI-MWCNT-MHGM composite aerogel exhibits porous structure with vertically aligned channels, strong mechanical properties, low thermal conductivity, and excellent thermal insulation, as well as broadband light absorption. As expected, the PI-MWCNT-MHGM evaporator shows a high evaporation rate (1.506 kg m−2 h−1) under 1 kW m−2 solar irradiation and excellent salt resistance, e.g., even when 1 g of NaCl was placed on the surface of the PI-MWCNT-MHGM, it could dissolve within 10 min. Moreover, the PI-MWCNT-MHGM possesses self-floating ability, combined with its eco-friendly, facile, and potentially scalable preparation method, the prepared aerogel may hold great potential for real applications. © 2022 Elsevier Ltd
