“…At last, after cooling at room temperature, the PDMS was picked off the SiO 2 negative replica after being cooled to the room temperature, then the PDMS positive replica was fabricated. The similar facile and novel method could be used combined with chemical etching to fabricate hierarchical surface structure on a copper sheet. Liu and Li produced lotus hierarchical structures on biomimetic shark skin via PDMS microreplication of shark skin, and then the hierarchical lotus structure was obtained through flame treatment.…”

decades, researchers have shown great interests in bionics, which was a new multidisciplinary subject inspired by biological characteristics and features to imitate it to build technology devices. [1] With the rise of biomimetic biomaterial researches, a lot of attention was paid on the observation of living organism, especially on plant leaves, such as lotus, rice, taro leaves, etc. [2] As the development of scanning electron microscope (SEM), a wealth of data dealing with SEM of plant surface has been published since 1960s. [3] The cuticular structure was investigated with regard to function, and substances that were secreted onto the cuticle had great effects on the surface properties, while intracuticular waxes were the main barrier to wettability. [4] Some kinds of special wettability like superhydrophobicity and superhydrophilicity were also found in other surfaces, such as self-cleaning lotus leaf, [5] hydrophilicity of red rose petals, [6,7] the anisotropic dewetting behavior on rice leaf, [8,9] hydrophobicity of shark skin, [10] gecko toe, [11] insect wings, [12] etc., and striking superhydrophobic force provided by a water strider's legs, [13] and they were all related to the unique microstructures on their surface. In fact, the special wettability of surfaces is attributed to the interaction of both the surface microstructures and surface covers. As the development and progress of the observation device, smaller nanosized structures were found on the microstructure, and better properties of multiscale hierarchical structure was shown then. [14] Wetting is a phenomenon that solid interface was transferred from solid-gas interface to solid-liquid interface, wettability was a kind of ability that a liquid could be unfolded on one solid surface. The wettability of surface could be characterized by contact angle (CA) of interface. Sliding angle (SA) and contact angle hysteresis were introduced to evaluate the highly valued superhydrophobicity and superhydrophilicity of surfaces. Superhydrophilicity was defied as that of CA was smaller than 5°, superhydrophobicity was defied as that of CA was greater than 150°, as well as a really small sliding angle. It is worth noting that many researchers applied themselves to excavate the theories under the phenomena. Young's equation, Wenzel equation, and Cassie-Baxter equation [15,16] were the representations of hundreds years of research results. Improving and developing Surfaces of plants and animals are evolved to optimal states to accommodate environments better after billions of years of natural selection. As the development of further study on bionics, surfaces with special wetting properties in nature are discovered, extremely related to the micro-/nanostructures on surface. The wetting models and wetting mechanism of several surfaces in nature are investigated, followed by lifting the veil of superhydrophobic field. Various facile, effective, and convenient methods for fabricating superhydrophobic surfaces are obtained and optimized in scientific research and ...

“…A variety of methods have been developed for the fabrication of many artificial superhydrophobic copper surfaces. For example, Guo and Yuan et al [7,9] mimicked the lotus leaf to fabricate superhydrophobic copper surfaces, respectively. Barthwal et al [6] developed a facile method for fabrication of copper oxide hierarchical structure on copper substrate by the oxidation of copper in hot alkaline solutions.…”

“…Superhydrophobicity can endow the copper with special properties, such as anti-frosting, anti-corrosion, and minimizing the resistance to flow in microfluidic devices [9]. Thus, the superhydrophobic coppers have greater potential applications even under some rigorous environment [10,11].…”

This article presents an effective and facile method for preparing the superhydrophobic copper surface with excellent corrosion resistance. The superhydrophobic copper surfaces were fabricated by oxidizing, heat-treating, and alkyl chains' grafting. The resulting copper plates take on the binary structure which is composed of a great deal of nanosheets and needle-like/rod-like fibers. Just grounded on both the micro-and nanoscale hierarchical surface and the grafted long alkyl chains, the resulting copper plates are endued with the excellent water repellence, while the water contact angle and sliding angle can reach 157.3°and 5°, respectively. As a result, the superhydrophobic copper plates get the outstanding corrosion resistance.

“…Forexample,superhydrophobic surfaces can be fabricated by creating structures that mimic the rough surface of the lotus leaf. [3,4] However,w hen such lotus-leaf-like surfaces are built from materials that respond to specific stimuli, they can exhibit switchable wettability.F or instance, alotus-leaf-like surface built from the photosensitive material TiO 2 can exhibit light-dependent switching. [5] To date,t he majority of materials that exhibit switchable wettability,a nd therefore could be used for fabricating such smart surfaces, comprise photo-sensitive inorganic oxides (for example, TiO 2 [4] and ZnO), [6] organic polymers (for example,l ightresponsive azobenzene-containing polymers, [7] temperatureresponsive poly-N-isopropylacrylamide, [8] and electricalresponsive polypyrrole), [9] self-assembled monolayers (SAMs;f or example,e lectrical-responsive 16-mercaptohexanoic SAMs [10] and pH-responsive mixed SAMs) [11] and counterion-exchange-responsive ionic liquids.…”

Switchable Surface Hydrophobicity–Hydrophilicity of a Metal–Organic Framework

et al. 2016

Materials with surfaces that can be switched from high/superhydrophobicity to superhydrophilicity are useful for myriad applications. Herein, we report a metal-organic framework (MOF) assembled from Zn ions, 1,4-benzenedicarboxylate, and a hydrophobic carborane-based linker. The MOF crystal-surface can be switched between hydrophobic and superhydrophilic through a chemical treatment to remove some of the building blocks.
