外文摘要：Solar-driven interfacial evaporation (ISE) has been identified as a potentially viable solution to the global water scarcity problem, with the capability of enabling energy-efficient desalination under ambient conditions. However, current ISE systems frequently exhibit signs of performance degradation, often attributable to salt accumulation and microbial contamination during extended operation. In this study, we present a multifunctional polyacrylamide-based interfacial evaporator (CAP) that integrates in situ synthesized carbon nanotubes/ silver nanoparticles (CNTs/AgNPs) composites. The AgNPs exhibit robust antibacterial activity, while the CNTs contribute to broadband photothermal absorption. The hydrogel matrix features tunable crosslinking density, which is optimised to facilitate water mobility and reduce the evaporation enthalpy. In conditions of illumination from a single sun, the CAP demonstrates a high evaporation rate of 2.3 kg center dot m- 2 center dot h- 1, exhibiting exceptional resistance to biofouling and salt crystallisation. Furthermore, the CAP produces freshwater with ion concentrations below 1 ppm, meeting WHO drinking standards. This work provides a scalable strategy to overcome the dual challenges of biofouling and salinity, paving the way for next-generation sustainable desalination technologies.
