Microfluidic fiber-spinning chemistry for hydrophilic–hydrophobic Janus membranes towards efficient interfacial solar evaporation

, achieving the purpose of salt resistance. On the other hand, the Janus structure also favors the redissolution of concentrated salts into raw water, further avoiding salt accumulation. This work offers a promising common strategy for constructing high-performance Janus evaporator, which will stimulate the development of seawater desalination.
