“…However, based on previous work [44][45][46][47][48][49][50][51][52][53][54] that recognized the importance of re-entrant texture (that is, convex topography, see Figure 2e; also explained in 'Critical role of re-entrant texture' section) in designing oil-repellent surfaces, several researchers have now engineered artificial (or synthetic) superoleophobic surfaces. 9,[55][56][57] Typically, most surfaces that repel lower surface tension liquids, such as oil, can also repel higher surface tension liquids, such as water. Consequently, most superoleophobic surfaces are also superhydrophobic.…”

Surfaces that display contact angles 41501 along with low contact angle hysteresis with essentially all high and low surface tension liquids, including water, oils and alcohols, are known as superomniphobic surfaces. Such surfaces have a range of commercial applications, including self-cleaning, non-fouling, stain-free clothing, drag reduction, corrosion prevention and separation of liquids. Such surfaces have thus generated immense academic and industrial interest in recent years. In this review, we discuss the systematic design of superomniphobic surfaces. In particular, we discuss the significance of surface energy, roughness and the critical role of re-entrant texture in obtaining the so-called Cassie-Baxter state with low surface tension liquids. We also discuss how hierarchical scales of texture can yield high contact angles and decrease the contact angle hysteresis of superomniphobic surfaces by reducing the solid-liquid contact area. On the basis of this understanding, we discuss dimensionless design parameters that allow for the systematic design of superomniphobic surfaces. We also review the current literature on superomniphobic surfaces, paying particular attention to surfaces that demonstrate good mechanical, chemical and radiation durability-traits that are essential for any commercial application of superomniphobic surfaces. Finally, we conclude by identifying the unresolved challenges in the fabrication of durable superomniphobic surfaces and highlight the future needs in the field.

“…In recent years, improving the corrosion resistance of metallic materials by surface superhydrophobization has become one of the hottest research areas in corrosion and protection. Compared to existing literature which has frequently reviewed the theories, preparation, and applications of superhydrophobic surfaces, [8][9][10][11][12][13][14][15] this review mainly focuses on the most recent developments of superhydrophobic surfaces for anticorrosion purposes. The authors review the typical preparation techniques of superhydrophobic anticorrosive surfaces and their anticorrosive performance, and provide a critical discussion of some mechanistic aspects of corrosion protection based on superhydrophobicity.…”

Due to their superior water-repelling effects, superhydrophobic surfaces have received increasing attention as a promising solution to corrosion of metallic materials. The present article introduces the fundamental theories behind superhydrophobicity followed by a comprehensive review of the recent progresses of this rapidly growing field over the past 5 years. A critical discussion over anticorrosion mechanisms of superhydrophobic surfaces is also provided. For many realistic applications, future efforts are pressingly demanded to prolong the corrosion resistance of these superhydrophobic surfaces. To this end, several important strategies and examples in designing stable, selfhealable, or inhibitor-loaded superhydrophobic surfaces are discussed.

“…Here, we show also that some of these monomers can lead to both hydrophilic and oleophobic properties. This unusual surface property is rare in the literature [27][28][29][30][31][32][33][34][35] but possible by combining hydrophilic and oleophobic materials, and can found other applications in oil/water separation, [36][37][38] for example.…”

Due to the much lower surface tension of oils in comparison to water, it is extremely difficult to obtain superoleophobic properties and also both oleophobic and hydrophilic properties. While the obtaining of superoleophobic properties needs extremely complex surface structures such as reentrant structures to impede the oil wetting, the obtaining of both oleophobic and hydrophilic properties needs the use of both oleophobic materials (fluorinated materials) and hydrophilic materials (charged or polar species). Here, by electropolymerization of original 3,4‐ethylenedioxythiophene derivatives containing both fluorinated chains (C8F17, C6F13, or C4F9) and highly polar linkers (thiocarbamate SCONH, carbamate OCONH, and urea NHCONH), the possibility to obtain superoleophobic properties and also both oleophobic and hydrophilic properties is reported for the first time. More precisely superoleophobic properties are obtained with different fluorinated chain lengths and linkers while the obtaining of both oleophobic and hydrophilic properties is possible only with the most polar urea NHCONH linkers.
