“…As for the SH-CP, in addition to three strong peaks belonging to CuO, there are two characteristic peaks at 2850 and 2918 cm −1 , which are generated by the stretching vibrations of the C−H bond, indicating that stearic acid is successfully grafted to the surface. 45 Additionally, the new absorption peak at 1585 cm −1 is attributed to the carboxyl group of stearic acid, which can form hydrogen bonds with the oxygen atom of CuO, 45,48,49 ensuring the stability of stearic acid on the CP surface. The results of FTIR spectra show that the surface of SH-CP has been successfully grafted with stearic acid.…”

Interfacial solar vapor generation (ISVG) is an emerging technology to alleviate the global freshwater crisis. However, high-cost, low freshwater collection rate, and salt-blockage issues significantly hinder the practical application of solar-driven desalination devices based on ISVG. Herein, with a low-cost copper plate (CP), nonwoven fabric (NWF), and insulating ethylene–vinyl acetate foam (EVA foam), a multistage device is elaborately fabricated for highly efficient simultaneous freshwater and salt collection. In the designed solar-driven device, a superhydrophobic copper plate (SH-CP) serves as the condensation layer, facilitating rapid mass and heat transfer through dropwise condensation. Moreover, the hydrophilic NWF is designed with rational hydrophobic zones and specific high-salinity solution outlets (Design-NWF) to act as the water evaporation layer and facilitate directional salt collection. As a result, the multistage evaporator with eight stages exhibits a high water collection rate of 2.25 kg m–2 h–1 under 1 sun irradiation. In addition, the desalination device based on the eight-stage evaporator obtains a water collection rate of 13.44 kg m–2 and a salt collection rate of 1.77 kg m–2 per day under natural irradiation. More importantly, it can maintain a steady production for 15 days without obvious performance decay. This bifunctional multistage device provides a feasible and efficient approach for simultaneous desalination and solute collection.

Carbon steel is widely used, but it is prone to corrosion, which can lead to safety accidents. In this study, a novel Ni‐SiC coating was synthesized on the surface of carbon steel using a one‐step electrodeposition method, and the influence of electrodeposition parameters on the wettability of the coating was investigated. This coating possesses abundant micro‐nanostructures on its surface, which, after being placed in a vacuum drying environment for 2 weeks, endows it with superhydrophobic characteristics. Due to its superhydrophobic properties and the rich micro‐nanostructures, the corrosion current density of this coating is 1/18.95 that of bare steel. After immersion in a corrosive medium for some time, the polarization resistance value of the coated sample was observed to be 13.05 times greater than that of bare steel, demonstrating its remarkable ability to enhance the corrosion resistance of the surface. The results of this study can provide a reference for the anticorrosion work on carbon steel.
