摘要: The treatment of hypersaline wastewaters with membrane distillation (MD) is significant but challenging, owing to the critical limitations of severe membrane wetting and fouling. Herein, a monolithic and self-roughened Janus fibrous membrane (FM) with asymmetrical superwettability was developed via sequential electrospinning and electrospraying in combination with thermal treatment. We detailedly discussed the formation mechanism of the roughness on the fiber surface via electrospinning/electrospraying technique and …
