Abstract

, 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.

A Synergistic Effect between Stearic Acid and (+)-α-Tocopherol as a Green Inhibitor on Ferritic Stainless Steel Corrosion Inhibition in 3.0% NaCl Solution

“…There exists a 'wide palette' of approaches on how to achieve a superhydrophobic surface [20], such as the sol-gel method, electrospinning, electrochemical methods, and layerby-layer method, which can be found in various review articles, like Darband et al [21] and Guo et al [22]. It has been confirmed that surfaces with hydrophobic properties can be an effective corrosion protection for numerous types of metal, such as steel [11,19,[23][24][25][26][27][28][29][30][31], copper [10,[32][33][34][35][36][37], nickel [38], zinc [39,40] Al-alloys [41][42][43][44][45][46] and Mg-alloys [47][48][49][50][51].…”

An Anodized Titanium/Sol-Gel Composite Coating with Self-Healable Superhydrophobic and Oleophobic Property

“…In the past few decades, the superhydrophobic and oleophobic surfaces have attracted sustained attention due to its self-cleaning properties (Liu et al, 2016;Qu et al, 2016;Wen and Guo, 2016;Wang et al, 2017;Li and Guo, 2019;Liu et al, 2019;Shen et al, 2019;Xing et al, 2019;Guo et al, 2020;Naderizadeh et al, 2020). The composite surfaces based on a combination of micro-nano structures and low surface energies were important to obtain superhydrophobic property (Liu et al, 2015;Ciriminna et al, 2016;.…”

“…The composite surfaces based on a combination of micro-nano structures and low surface energies were important to obtain superhydrophobic property (Liu et al, 2015;Ciriminna et al, 2016;. Water droplets easily roll on such surfaces at a small angle of inclination and removed the dust from the surface (Bai et al, 2016;Falde et al, 2016;Giacomello et al, 2016;Milionis et al, 2016;Rao et al, 2016;Wen and Guo, 2016;Fu et al, 2017;Long et al, 2017;Alamri et al, 2018;Kim et al, 2018). With the increasing use of titanium in daily life, its superhydrophobic and oleophobic properties have attracted increasing attention.…”

Facile Fabrication of Superhydrophobic Surface from Fluorinated POSS Acrylate Copolymer via One-Step Breath Figure Method and Its Anti-Corrosion Property

“…For a flat surface, theoretical calculation shows that the highest contact angle of water could reach 120 • [8,9]. It is well known that creating appropriate roughness on a hydrophobic surface or modifying a rough one by low-surface-energy materials are two main routes to obtain super-hydrophobic surfaces [10].…”
