“…More recently, researchers utilized stimuli‐responsive materials to fabricate controllable oil–water separators that can tackle more challenging problems . Stimuli introduced to control the separation can be categorized as physical signals, including temperature, light, voltage, magnetic field, pressure, and chemical signals, such as pH, Hg ion, gas molecules, ammonia . Xin et al fabricated a TiO 2 doped PVDF nanofiber, and the smart membrane with microscale pores was obtained by electrospinning of the special nanofiber (Figure g,h).…”

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.

“…The PNIPAAm phase transition has been used to switch between hydrophobic and hydrophilic environments 111. The same concept was successfully introduced in a polymer decorated membrane to separate oil‐in‐water emulsions in a controlled way 112. Alternative strategies to carry out oil/water filtrations have been reported by Li et al, who used pH‐responsive membranes based on poly(4‐vinylpyridine) copolymers 113.…”

Interactive materials are at the forefront of current materials research with few examples in the literature. Researchers are inspired by nature to develop materials that can modulate and adapt their behavior in accordance with their surroundings. Stimuli‐responsive systems have been developed over the past decades which, although often described as “smart,” lack the ability to act autonomously. Nevertheless, these systems attract attention on account of the resultant materials' ability to change their properties in a predicable manner. These materials find application in a plethora of areas including drug delivery, artificial muscles, etc. Stimuli‐responsive materials are serving as the precursors for next‐generation interactive materials. Interest in these systems has resulted in a library of well‐developed chemical motifs; however, there is a fundamental gap between stimuli‐responsive and interactive materials. In this perspective, current state‐of‐the‐art stimuli‐responsive materials are outlined with a specific emphasis on aqueous macroscopic interactive materials. Compartmentalization, critical for achieving interactivity, relies on hydrophobic, hydrophilic, supramolecular, and ionic interactions, which are commonly present in aqueous systems and enable complex self‐assembly processes. Relevant examples of aqueous interactive materials that do exist are given, and design principles to realize the next generation of materials with embedded autonomous function are suggested.

“…[8][9][10][11][12][13] Thus, researchers tend to focus on smart superwetting materials with thermal-responsive, electro-responsive and pH-responsive properties. [14][15][16][17][18] Among all of the stimuliresponsive materials, photo-responsive materials were an emerging class with attractive superiorities, which have become a hot research topic in recent years, especially in the eld of oil/water separation. [19][20][21] The utilization of photoswitchable materials can effectively avoid contact with materials during the response process, which decreases the materials' contamination and increases the reusability of the materials.…”
