| Summary: | It should be noted that the one-way transportation of liquids is of great significance to the separation or collection process and the manipulation of microfluids can effectively solve many practical problems, such as oil-water separation, fog-harvesting and so on. Fortunately, asymmetric wettability endows bioinspired Janus membranes (JMs) with special driving forces for unidirectional liquid transportation, which is of great potential in microfluidic manipulation. In this review, recent research advances in JMs are summarized with the focus on the development process, basic wetting properties and classifications of JMs. Based on different prepared materials, bioinspired special JMs can be divided into three categories as follows: polymeric Janus membranes, polymeric-inorganic Janus membranes and inorganic Janus membranes. Next, special attention is paid to the systematic physical mechanisms of unidirectional transport. Also outlined are current and potential applications in oil-water separation, membrane distillation, fog-harvesting, sensors and so on. Finally, a perspective on the future of bioinspired superwetting JM research and development is proposed.
A comprehensive insight about Janus membranes is provided from their unidirectional transport behaviors and systematic physical mechanisms to asymmetric-wettability-dominated applications, which brings a new perspective to the manipulation of microfluids. |

| Bibliography: | Miss Hui Zhou joined Prof. Guo's biomimetic materials of tribology (BMT) group at Hubei University in 2018 to pursue her PhD degree. Her current scientific interests are focused on superwetting Janus membranes with unidirectional transport behaviors and their multiple applications. Professor Zhiguang GUO received his PhD from Lanzhou Institute of Chemical Physics (LICP), Chinese Academy of Sciences (CAS) in 2007. After that, he joined Hubei University. From Oct 2007 to Aug 2008, he worked at University of Namur (FUNDP), Belgium, as a post-doc. From Sep 2008 to Mar 2011, he worked in Funds of National Research Science (FNRS), Belgium, as a "Charge de Researcher". During Feb 2009 to Feb 2010, he worked in the Department of Physics, University of Oxford, UK, as a visiting scholar. Now he is a full professor in LICP financed by the "Top Hundred Talents" program of CAS. Until now, he has published more than 250 papers about the interfaces of Materials.
