摘要:
 膜蒸馏作为一种新兴的膜分离技术,在海水淡化和废水处理等方面受到了越来越多的关注。然而,在实际应用中,进料液中含有多种低表面能污染物,容易导致疏水膜润湿。近年来全疏膜因其能抵抗不同液体润湿,缓解膜蒸馏过程中的膜润湿问题而备受关注。本文简述了全疏膜性能的关键参数,具体介绍了纳米粒子掺杂膜、静电纺丝膜和Janus膜这三类常用的全疏膜的制备方法及其用于膜蒸馏的性能,提出全疏膜的设计策略与未来发展趋势。
 Membrane distillation (MD) is an emerging separation technology, which has received great attention in seawater desalination and wastewater treatment. However, the feed solutions contain a variety of low surface energy pollutants in practical applications, which will make the traditional hydrophobic membrane wetting. Currently, omniphobic membranes have attracted much attention because they can resist the wetting of all liquids and alleviate the wetting phenomenon in MD process. In this paper, the commonly used parameters for evaluating the performances are briefly discussed. Then the research progress of three commonly omniphobic membranes in recent years is introduced in detail, which are nanoparticle incorporated membranes, electrospun membranes and Janus membranes. Finally, the design strategies and future development trends of omniphobic membranes are summarized.
