Electrostatically Self-Assembled Coaxial-Roll Evaporator: Achieving Ultra-High Efficiency and Durability for Sustainable Seawater Desalination and Irrigation

with 97.19% efficiency, maintaining structural integrity under extreme conditions including pH = 1-14, 90 °C temperatures, ultrasonic agitation, and mechanical compression. After 20 consecutive cycles of operation in real seawater, the performance retention rate reaches 94.87%. The desalinated water meets WHO drinking water standards and supports normal wheat growth. Overall, this study provides innovative insights and practical solutions for highly efficient, salt-tolerant, antimicrobial, and scalable solar seawater desalination as well as agricultural irrigation technology.
