Preparation and Antiscaling Application of Superhydrophobic Anodized CuO Nanowire Surfaces

The energy problem has been a matter of some concern worldwide over the past 20 years. On the opposite side of energy production, energy loss is another crucial problem of current energy due to the low efficiency of heat transfer from scale deposition. However, less attention has been paid on the further development of advanced antiscaling interfacial materials, which may provide promising ways to save energy by reducing scale fouling. Herein, the development of antiscaling strategies is summarized from the basic theories and fabrication methods to antiscaling interfacial materials with potential applications. First, the mechanism of scale formation and the corresponding effect on thermal conductivity are introduced. Second, the typical fabrication approaches of antiscaling interfacial materials are briefly described. Finally, the performance, potential applications, future challenges, and opportunities of the advanced antiscaling interfacial materials are comprehensively discussed.

, 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.

“…24 Recently, some attempts based on superwettability regulation [25][26][27][28] , such as superhydrophobic copper oxide coatings with nanowires or nanoflakes, have been employed to prevent the growth and adhesion of mineral crystals. 29,30 However, the superhydrophobicity of surfaces may be gradually lost after immersion in a fluid for a long time, which probably hinders further applications of such system. 31 Therefore, it remains a great challenge to develop functional coatings with high anti-adhesion against mineral scales.…”

The unexpected adhesion of certain inorganic minerals on solid surfaces is constantly a source of severe problems in daily life and industrial production, including scales in water pipes. Inspired by the nanostructured inner surface of normal renal tubules, we design a superhydrophilic nanohair coating composed of a poly(hydroxyethyl methacrylate) (PHEMA) hydrogel, which shows high anti-adhesion against mineral scales under flow conditions. Even at a high temperature of 80°C, the nanohair hydrogel coatings still show excellent anti-scaling performance compared to a flat hydrogel coating and a commercial water pipe with a polyvinylchloride (PVC) surface. The anti-scaling experiments and theory simulation reveal the crucial role of superhydrophilicity and fluid-assisted motion of the nanohairs in the anti-adhesion property. This study may provide promising insight into the design of high anti-adhesion coatings for resisting mineral scale attachment in water management systems.
