“…This may be related to the strong hydrophobic force provided by the densely packed hydrophobic layer. [40,42] Furthermore, AD-6 with a much thicker hydrophobic layer is also tested (Figure S10, Supporting Information). Ascribed to the large thickness and dense stacking of nanofibers for the hydrophobic layer, the water droplet is still not be absorbed into the hydrophilic layer, even when the 5 mm-thick BC-g-PAANa layer with higher water absorption is used.…”

Simultaneous infection and exudate management remain a great challenge in wound treatment. As one of the most promising approaches, current asymmetric dressings are basically prepared through electrospinning with different kinds of materials, and the interfacial interaction remains unexplored. Herein, the first single‐substrate‐based asymmetric dressing with a well‐entangled interface, large absorptive capacity, effective fluid reflux prevention, excellent antibacterial, and antipenetration properties is developed. The asymmetric dressing is composed of layered hydrophilic and hydrophobic bottlebrushes (sodium polyacrylate and polystyrene‐functionalized bacterial cellulose), which are assembled using stepwise vacuum filtration, accompanied by loading triclosan into the solution of hydrophilic bottlebrushes. The biocompatibility and feasibility of the asymmetric dressing pave the way in real wound management.

Janus materials with anisotropy shapes and chemical compositions, including Janus particles, Janus nanosheets, and Janus membranes, have a great significance in the development of new functional materials and expansion of the properties and applications of materials. This review summarizes recent works on Janus materials of preparation, application, assembly, and calculation. First, we briefly sort out the methods of preparing Janus particles and discuss the factors influencing the structure, shape, and size of Janus particles, pointing out their advantages and the direction of improvement. Then, we introduce in detail the applications field from a single Janus particle, assembly of Janus particles, 2D Janus nanosheet, and Janus membrane. We summarize the recent research on the self-assembly of Janus particles and point out the role of the combination of computational simulation and experiment in the research of Janus material. Finally, the research process of Janus materials is reviewed, and the development tendencies of Janus materials and the problems to be solved are summarized.

“…Based on the above considerations, we will investigate a novel multifunctional Janus-type membrane as a protective coating for the anode of Al-air battery. At present, Janus-type membranes have been widely used in battery diaphragms, [18] corrosion protection, [19] high-efficiency catalyst, [20] and drug delivery. [21] In this work, we creatively demonstrate a composite Janus-type membrane incorporating ZnO and MoS 2 .…”

Novel multifunctional Janus‐type membrane with both hydrophobic and anticorrosion abilities is constructed on the surface of aluminum (Al), using MoS2 as a hydrophobic layer and ZnO as a corrosion‐resistant layer. Al anode coated with the Janus‐type membrane is used as an example to study the specific property of the as‐prepared Janus‐type membrane. In the Al–air battery, the self‐corrosion of the Al anode is well inhibited since the Janus‐type membrane can block the invasion of excess hydroxide ions and water molecules simultaneously. The results show that the inhibition efficiency of the Janus‐type membrane is as high as 79.2%. Furthermore, the electrochemical measurements demonstrate that the discharge specific capacity of the Al–air battery with the Janus‐type membrane can reach up to 2095 mAh g−1, approximately two times as much as that of traditional batteries. The integrated strategy of combining hydrophobic and anticorrosion membrane is a novel method for corrosion protection of metal electrode. This Janus‐type membrane holds a great potential toward corrosion inhibition for the other metal in alkaline environment as well.
