Interfacial solar evaporation is a sustainable and effective method that uses solar energy to produce freshwater. As this technology continues to develop, the ability of interfacial solar evaporators to tolerate high salt concentrations and achieve stable evaporation has gradually improved. Some evaporators can even achieve complete separation of water and solutes, resulting in zero liquid discharge. Here, we discuss strategies for interfacial solar evaporators for treating high-salinity wastewater and achieving zero liquid discharge. We particularly focus on representative management strategies, including timely removal of salt crystals and prevention of salt deposition on photothermal materials. Additionally, we present three design ideas for evaporators, including the fundamental principles behind these strategies. Current challenges and future research opportunities are proposed.

This work demonstrated the hydrothermal synthesis of bimetallic MOF(Zn/Cu-BTC) for CO ₂ adsorption with high CO ₂ /N ₂ adsorption selectivity.

Superhydrophobic fabrics with an outstanding self-healing performance in sunlight have been prepared by loading all-water-based octadecylamine@polydopamine core–shell nanospheres.

The surfactant-assisted preparation of carbon nanotube (CNT)/polymer composites has attracted the attention of scientists around the world. Here, CNT/epoxy nanocomposites were prepared using sodium carboxymethyl cellulose (CMC). The effect of CMC on the curing behaviors of epoxy resin (E44) and CNTs/E44 was studied using differential scanning calorimetry (DSC). The curing kinetics of the CMC/CNTs/E44 systems were examined using methods where the activation energy (E) is a constant and where E is a variable, respectively. The change of E with the conversion (α) was calculated using the Starink isoconversional method. For the E44 system, a significant variation of E was observed when the conversion increased from 0.05 to 0.95. The E variable method was introduced to this system to describe this phenomenon. In contrast to the method where E is a constant, the E variable method has better agreement with the experimental data. With these two methods, the curing kinetics of the CMC/CNTs/epoxy system can be understood comprehensively and accurately. Ultimately, the dynamic mechanical properties of neat E44, CMC/E44 and CMC/CNTs/E44 were investigated and compared, which showed that CMC/E44 had a higher storage modulus (E_m) than the neat E44 and CMC/CNTs/E44 systems, and the CMC/CNTs/E44 system had a higher glass transition temperature (T_g) and damping factor (tan δ) than the neat E44 and CMC/E44 systems.

An acrylic acid-modified epoxy phosphate resin coating was synthesized by a four-step method marked “A-B-C-D”, and it was used as an efficient protective layer for steel structures. The coating exhibited good properties, mainly including water resistance (≥240 h), salt spray resistance (≥300 h), surface drying time (≤1 h), and adhesion (≥6.5 MPa).
