Abstract

at a temperature difference of 40 °C, while maintaining salt rejection above 99% and stable long-term operation. This improvement is attributed to the synergistic effects of CB-induced localized photothermal heating and PVA-enhanced surface hydrophilicity, which collectively reduce temperature polarization and facilitate efficient heat and mass transfer. These results highlight a scalable, cost-effective strategy for fabricating durable photothermal membranes, thereby advancing solar-driven desalination and sustainable water treatment.
