“…55 The molecular self-assembly has been reported in numerous research papers. 20,7684 It may be achieved in different manners, such as solution immersion process, 16,24,82 roomtemperature vacuum approach, 81 chemical vapor deposition, 20 spraying process, 77 flame spray pyrolysis, 83 and so on. For example, Lu et al reported a cost-effective method to fabricate a graphene-modified foam via the convenient thermal reduction process of graphene oxide along with the reduced graphene's self-assembly.…”

“…Sun et al fabricated self-healing, robust, and superhydrophobic coatings on fabrics through all spraying layer-by-layer (LbL) assembly process. 77 In this study, the LbL assembly process was conducted by subsequently spraying three polyelectrolyte complexes, namely poly(allylamine hydrochloride), sulfonated poly(ether ether ketone) (PAHSPEEK), and poly(acrylic acid) (PAA) to form high porous and rough coatings with nanostructures satisfying the need of superhydrophobicity. Taking the advantage of positively charged poly(diallyldimethylammonium chloride) (PDDA) to strengthen their adhesion toward coatings, this superhydrophobic coating also has self-healing ability.…”

“…For instance, the spraying LbL assembly has some prominent advantages over the dipping LbL assembly in terms of facility to tailor compositions and film structures, allowing the films easily on large areas of the substrate and recover through simply re-spraying. 77 Importantly, self-assembly can be achieved on fabrics, metal, and various substrates.…”

, as a visiting scholar. Now he is a full professor in LICP financed by "Top Hundred Talents" program of CAS. Till now, he has published more than 130 papers about the interfaces of Materials.Miss Qiuying Wen joined Prof. Guo's biomimetic materials of tribology (BMT) group at University of Hubei in 2015 in pursuing her Ph.D. degree. Her current scientific interests are devoted to designing and fabricating applicable superhydrophobic surfaces by using environmentally friendly materials and studying their corresponding applications. AbstractAs one of the most important parts in the surface and interface science, superhydrophobic surfaces play a significant role in both the fundamental research of functional materials and various applications. Therefore, this research field attracts more and more researchers' attention from all over the world. In the past decades, a large number of biomimetic functional superhydrophobic surfaces have been fabricated inspired from the natural superhydrophobic phenomenon. In this paper, we reviewed the recent advances in the research field of superhydrophobic surfaces, mainly including basic principles, fabrication methods, and applications three aspects. In order to facilitate the comparison, fabrication methods have been divided into three classes at first: coating methods, deposition methods, and the method of direct reproduce (template method). Further, each method is subdivided into several more specific sections such as coatings covering self-assembly coating, grafting coating, electrodeposition, electroless deposition, and so on, according to the theory of the coatings bonding with substrates. For each subsection, the corresponding comments of advantages and partly drawbacks have been summarized. In addition, the peculiar applications of superhydrophobic surfaces, such as waterproof function, antibacterial, antibiofouling, antiscaling, anti-icing, and so on, are also mentioned briefly. Finally, current challenges for this research field are also proposed. The aim of this review is to give a brief and crucial overview of the recent advances in the fabrication of superhydrophobic surfaces.

“…To overcome this problem, self-healing abilities can be introduced into superhydrophobic coatings to enable the repair of the damaged surface chemistry and/or morphology, which can significantly extend their service lives [15][16][17] . For example, inorganic/organic micro-/nanocontainers have been used in superhydrophobic coatings for storing low-surface-energy materials [18][19][20][21] .…”

AbstractThis work introduces a new self-healing superhydrophobic coating based on dual actions by the corrosion inhibitor benzotriazole (BTA) and an epoxy-based shape memory polymer (SMP). Damage to the surface morphology (e.g., crushed areas and scratches) and the corresponding superhydrophobicity is shown to be rapidly healed through a simple heat treatment at 60 °C for 20 min. Electrochemical impedance spectroscopy (EIS) and scanning electrochemical microscopy (SECM) were used to study the anti-corrosion performance of the scratched and the healed superhydrophobic coatings immersed in a 3.5 wt% NaCl solution. The results revealed that the anti-corrosion performance of the scratched coatings was improved upon the incorporation of BTA. After the heat treatment, the scratched superhydrophobic coatings exhibited excellent recovery of the anti-corrosion performance, which is attributed to the closure of the scratch by the shape memory effect and to the improved inhibition efficiency of BTA. Furthermore, we found that the pre-existing corrosion product inside the coating scratch could hinder the scratch closure by the shape memory effect and reduce the coating adhesion in the scratched region. However, the addition of BTA effectively suppressed the formation of corrosion product and enhanced the self-healing and adhesion performance under this condition. Importantly, we also demonstrated that the coating can be autonomously healed within 1 h in an outdoor environment using sunlight as the heat source.

“…For instance, Li et al fabricated a self-healing superhydrophobic coating by spraying layer-by-layer (LbL) assembly of poly(allylamine hydrochloride)-sulfonated poly(ether ether ketone), poly(acrylic acid) and healing agents, such as peruorooctanesulfonic acid lithium salt (PFOS) or uoroalkyl silane (POTS), on the surfaces of substrates. 20 When the surface of this polyelectrolyte coating was damaged, the stored POTS or PFOS in the coating could migrate to the damaged surface for healing the wettability under a minor humid condition. Esteves et al reported a selfreplenishing superhydrophobic coating consisting of a dispersion consisting of dual-sized silica nanoparticles and uoroalkyl-terminated polymeric dangling chains.…”

Superhydrophobic coatings have received great attention over the past decades because of their specific performances, but most of them may lose their superhydrophobicity under harsh conditions especially in outdoor applications. In this paper, UV and pH dual stimuli-responsive self-repairing waterbased superhydrophobic coatings were prepared based on TiO 2 with photocatalysis and pH-responsive microcapsules, which were durable against UV irradiation and chemically stable in contact with alkaline or acidic aqueous solutions. These coatings are an environment-friendly waterborne system and could be easily coated on various substrates. What is more, they can restore their superhydrophobicity and self-cleaning ability under UV light even after mechanically damaged or contaminated with organics.Moreover, this superhydrophobic coating was immersed into 5 wt% NaCl aqueous solutions for 24 h or underwent ten icing/melting cycles, their surfaces could also recover the superhydrophobicity under pH or UV stimuli.
