Self‐Repairing and Damage‐Tolerant Hydrogels for Efficient Solar‐Powered Water Purification and Desalination

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 31(40)

Published: July 10, 2021

Abstract Solar‐driven interfacial evaporation has emerged as an innovative and sustainable technology for efficient, clean water production. Real‐world applications depend on new classes of low‐cost, lightweight, robust materials that can be integrated into one monolithic device, which withstands a variety realistic conditions open water. Self‐repairing building blocks are highly desired to prevent permanent failures, recover original functions maintain the lifetime steam generators, although related studies scarce date. For first time, monolithic, durable, self‐floating generator with well‐defined structures is demonstrated by integrating self‐healing hydrogels through facile processes in surface modulation device fabrication. High stable rates over 2.0 kg m −2 h −1 attained under 1 sun both fresh brine broad range salinity (36–210 g ). The solar desalination performance among best‐performing generators surpass majority devices constructed composite polymers structural components. This study provides perspective highlights future opportunities damage‐tolerant simultaneously improve performance, durability, real‐world applications.
