“…In addition to the abovementioned superhydrophobic surfaces, superomniphobics urfaces are also significant because they can repel many liquids, including both water and oils. [42] To the best of our knowledge, to date, the superomniphobic SMP surface has only recently been reported by Wang et al [43] In their Figure 10. a) Schematicillustration of surfacem icrostructure variation between two states.SEM images for the surfacebefore (b) and after (c) the introduction of ag roovestructure.…”

Control of surface wettability is very important, and can be realized by controlling surface chemistry or microstructures. Compared with surface chemistry, smart control of surface microstructure is more difficult. Recently, shape memory polymers (SMPs) have advanced to allow control of the surface microstructure and wettability, and thus, demonstrate excellent controllability and many novel functions. In this Minireview, recent achievements in wetting control on SMP surfaces with general hydrophobic, superhydrophobic, superomniphobic and superslippery properties are presented. Particular attention is paid to superhydrophobic surfaces, which display many novel functions, such as switchable isotropic/anisotropic wetting and reprogrammable gradient wetting. Furthermore, a new strategy that combines responsive molecules with the SMP microstructure is also described; this can be used to realize precise wetting control based on coordinated regulation of both surface microstructure and chemistry.

“…[61] However, for chemical etching, precise control of surface morphology is difficult, especially for miniature structures. [11] Compared with wet chemical etching, electrochemical etching, which is also named anodic dissolution, can offer better controllability and reproducibility. By varying the anodic current density, electrolyte solution, etching time, the structure can be finely tuned.…”

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.

“…Examples of naturally occurring superwettability structures are plentiful, such as the lotus leaf, rose petals, the compound eyes of the mosquito, the legs of the water strider, the back of the desert beetle, the wings of butterflies, and the pitcher plant, to name a few. Intensive efforts have been devoted to elucidate the underlying mechanism between the micro/nanoscale hierarchical architectures of these natural objects and the enabled functionalities . For instance, the self‐cleaning property of the lotus leaf, the water‐walking ability of water striders, the fog collection of the beetle's back, and the insect‐capturing ability afforded by the slippery surface of pitcher plants .…”

Biological systems have evolved over billions of years to develop wetting strategies for advantageous structure-property-performance relations that are crucial for their survival. The discovery of these intriguing relationships has inspired tremendous efforts to investigate the micro/nanoscale features of naturally occurring structures with superwettability. Researchers have since developed new methods and techniques to construct artificial materials that mimic natural structures and functionalities. Here, a brief review of natural hierarchical architectures with liquid repellent properties is presented, and the critical underlying mechanism is summarized with an emphasis on the micro/nanoscopic architectures. The state-of-the-art micro/nanofabrication techniques for creating bioinspired hierarchical superwettability structures that are categorized by random and exquisite features are also reviewed, followed by an overview of their emerging applications, with special attention to biomedical-related fields. The development of fabrication techniques enhances capabilities relative to those of living systems, paving the way toward advanced structural materials with superior functions and unprecedented characteristics for potential applications.
