Understanding the relationship between liquid manipulation and micro‐/nanostructured interfaces has gained much attention due to the wide potential applications in many fields, such as chemical and biomedical assays, environmental protection, industry, and even daily life. Much work has been done to construct various materials with interfacial liquid manipulation abilities, leading to a range of interesting applications. Herein, different fabrication methods from the top‐down approach to the bottom‐up approach and subsequent surface modifications of micro‐/nanostructured interfaces are first introduced. Then, interactions between the surface and liquid, including liquid wetting, liquid transportation, and a number of corresponding models, together with the definition of hydrophilic/hydrophobic, oleophilic/olephobic, the definition and mechanism of superwetting, including superhydrophobicity, superhydrophilicity, and superoleophobicity, are presented. The micro‐/nanostructured interface, with major applications in self‐cleaning, antifogging, anti‐icing, anticorrosion, drag‐reduction, oil–water separation, water collection, droplet (micro)array, and surface‐directed liquid transport, is summarized, and the mechanisms underlying each application are discussed. Finally, the remaining challenges and future perspectives in this area are included.

A highly anti‐oil fabric membrane is synthesized by surface grafting of zwitterionic poly(sulfobetaine methacrylate) (PSBMA) onto the fabric surface. The fabric membrane is first enzymatically modified to create more reactive amine groups on the surface. A surface‐initiated atom transfer radical polymerization (SI‐ATRP) reaction is then performed to modify the fabric membrane surface with a dense PSBMA brush layer. Surface characterization indicates that the brush‐grafted fabric membrane exhibits increased surface roughness and improved superhydrophilicity. The PSBMA‐modified silk fabrics show a very large contact angle for oil droplets in water, and have excellent oil resistance in air and in water–oil mixtures.

“…Ozonation followed by treatment with microalgae was very effective in reducing caffeine and carbamazepine, organic matters, and inorganic nutrients from ROC in a single bioreactor. Deng et al (2019) fabricated superhydrophilic and underwater superoleophobic membranes using poly(methyl methacrylate-co-glycidyl methacrylate) and polyethylethyleneimine to blend with PVDF for in situ cross-linking copolymerization. The modified PVDF membrane is very effective in oil/water emulsion separation, and the membrane can withstand repeated long-term operation due to the cross-linking property.…”
