Metals are indispensable engineered materials for day-to-day life. Researches focused on metallic surfaces with superlyophobicity (superhydrophobicity, superoleophobicity, underwater superoleophobicity and slippery characteristic) have attracted much attention recently. Nature is a magician that gives each organic life a unique advantage. Researchers have created a large number of biomimetic superlyophobic metallic surfaces through various approaches. These biomimetic superlyophobic metallic surfaces exhibit advantages in many applications, such as self-cleaning, corrosion resistance, anti-icing, and drag reduction. In this review, the specific fabrication and applications of biomimetic superlyophobic metallic surfaces were reported. The remaining challenges and future outlook of biomimetic superlyophobic metallic surfaces were preliminarily analyzed. It is hoped that the review will be essential for broadening the scope of potential applications of metals and providing a powerful reference for future research on metal-based advanced functional materials.

“…[21] In the past decade, superhydrophobicsuperoleophilic membranes have been extensively studied and used to remove oil from aqueous mixtures, but they usually suffer from structural fouling due to the adsorption of oils onto the intrinsically oleophilic surfaces. [22,23] Superhydrophilic-superoleophobic surfaces, on the other hand, are free from the oil contamination problems due to their intrinsic oil-repellent properties. [24] However, it is highly challenging to construct such materials since a superoleophobic surface inherently exhibits superhydrophobicity.…”

Smart materials with unique surface wetting properties have attracted considerable interest, particularly for oil/water separation, where oil can cause severe environmental damage. Despite 2 the considerable progress made in the past decade, critical challenges remain in scaling up, as smart materials are either expensive to fabricate or involve complicated, energy-intensive, and/or time-consuming production processes. In this work, an ultra-facile approach to fabricate hierarchical Zeolitic Imidazolate Framework-L (ZIF-L) mesh films with switchable superwettability for efficient oil/water separation was reported for the first time. A thick, continuous layer of well-intergrown ZIF-L nanoplates with an average aspect ratio of ~25 was successfully synthesized on various stainless steel (SS) meshes at ambient conditions. The ZIF-L mesh films exhibited extraordinary in-air superamphiphilic, underwater superoleophobic and underoil superhydrophobic properties, and showed outstanding performance in solely-gravitydriven oil/water mixture separation. Interestingly, a prewetting-induced switchable permeation function was found for the hierarchical ZIF-L surface, truly achieving "oil-blocking" and "water-blocking" separation. The ZIF-L mesh films demonstrated superior cyclic separation performance for a variety of oil/water mixtures with separation efficiencies above 99.99% and satisfactory chemical and mechanical stabilities even in harsh conditions. Their rapid and energy-efficient fabrication is therefore highly promising for cost-efficient and large-scale production for widespread applications in oil/water separation.

“…And PDMS-b-PF is obtained a very low surface tension [4], shows strong hydrophobic/oilphobic and self-cleaning properties [5,6]. The microphase separation is an important feature of the fluorosilicone block copolymers which is one of the hot topics in the field of organic fluorine and silicon materials in recent years [7][8][9], and itmakes the function of the polymer greatly improved and the application domain widened [10,11]. For example, Huang L. B et al [12] added a certain amount of styrene and 1,3,5-tris (1,3,5-(3',3',3'trifluoropropyl) ring siloxane block copolymers to the polystyrene and the surface properties of the blends were studied.…”

Fluorosilicone polymer is a new type of structure of the fluorine silicon block polymer. Because it combines the excellent properties of organic silicone and organic fluorine compounds, it has a wide range of uses and becomes a hot issue in the field of materials. In the paper, A series of novel poly(2,2,3,4,4,4-hexafluorobutyl methacrylate)-blockpoly(dimethylsiloxane)-block-poly(2,2,3,4,4,4-hexafluorobutyl methacrylate)s (PHFBMA-b-PDMS-b-PHFBMA) were synthesized by atom transfer radical polymerization (ATRP) with different molecular weight prepared polydimethylsiloxane macroinitiator as raw materials. The effects of the fluorine and silicone content on the hydrophobic and oleophobic properties of prepared triblock copolymers were also investigated. The structure and composition of the copolymers were analyzed and identified by infrared spectroscopy (IR) and nuclear magnetic resonance (NMR). The average molecular weight and molecular weight distribution of the prepared PHFBMA-b-PDMS-b-PHFBMA were evaluated by gel permeation chromatography (GPC). The surface energy of the triblock copolymers was calculated from the contact angle reaches as low as 10.43 mN/m through the Owens-Wendt-Rabel-Kaelble method, with the fluorine content of triblock polymer was 19.0 wt%. Atomic force microscopy (AFM), differential scanning calorimetry (DSC) and X-ray photoelectron spectroscopy (XPS) indicated that there were Obvious nanoscopically microphase separation on the surface of the prepared triblock copolymers and the fluoride contents in the block polymer of the fluorine silicon block were more likely to migrate to the surface.
