摘      要：Membrane distillation(MD)utilizing low-grade thermal energy can be used to effectively desalinate hypersaline brines with a high freshwater recovery for water *** flux and durability are the two main indices used to evaluate MD membrane *** the past decade,electrospun nanofibrous distillation membranes(EFDMs)with a low mass transfer resistance have garnered increasing attention in MD research,owing to their high porosity and interconnected-pore ***,on the one hand,the pores of EFDMs compared to those of phase-inversion membranes are easily deformed and impacted by water flow,reducing membrane flux;on the other hand,the general hydrophobic interface is susceptible to being wetted,fouled and scaled during the desalination/concentration process,resulting in MD *** review will present a comprehensive discussion of the recent progress in electrospun nanofibers for the MD of hypersaline wastewaters with a focus on designing specially wettable membrane interfaces and welding-pore structured membranes to enhance MD distillation efficiency and durability ***,the challenges and perspectives of MD in treating hypersaline wastewaters are also provided as a guide for future research on sustainable and clean freshwater recovery.
