This article investigates an intelligent composite membrane material featuring reversible transitions between superhydrophobic and superhydrophilic surfaces. First, epoxy resin porous membranes (EP) were fabricated via the breathing figure (BF) approach. The relationship between the curing degree of epoxy resin, the polymer concentration, and the surface wettability of the porous membranes was systematically explored. After growing SiO 2 on the surface of the porous film, an EP/SiO 2 superhydrophobic composite film was successfully prepared (WCA≈159°). The surface morphology of the sample was observed by scanning electron microscopy, and combined with the contact angle measurement results, the optimal growth time was determined to be 2.5 h. Interestingly, after the samples were placed in a high-humidity environment for 10 h, they changed from superhydrophobic to superhydrophilic (WCA = 0°), and then regained their superhydrophobicity after being heat-treated for 40 min. The analysis results of XPS scanning of the sample surface indicate that the reversible switching of wettability is realized through the alteration of surface chemical composition. This mode of reversible transformation between superhydrophobicity and superhydrophilicity realized through water absorption and heating will possess highly potential application values in technical domains such as oil–water separation, smart materials, and self-cleaning.

Developing robust and durable superhydrophilic surfaces on polyethylene terephthalate (PET) films is critical for advancing their applications in self-cleaning and biomedical technologies. In this study, a coating solution containing polyethyleneimine and HDI polyisocyanate was bar-coated onto PET film surfaces and subsequently cross-linked to form a dense R-NH-CO-NH-R' covalent network. After modification, the PET film surfaces demonstrated superhydrophilicity (WCA=0°) accompanied by a significant increase in surface energy to 79.4 mN/m, while achieving excellent 5B-grade adhesion. Furthermore, when exposed to 40-hour immersion in aqueous solutions, the modified surfaces maintained their superhydrophilicity (0° WCA) with essentially unchanged surface energies. The coatings showed near-complete surface coverage along with substantial covalent bonds retention. Such crosslinking construction approach via bar-coating exhibits promising potential for PET films in superhydrophilic applications.

This paper studied the coalescence, spreading, and rebound of two droplets with different temperatures on a superhydrophobic surface. When the temperature of the impacting droplet was the same as that of the stationary droplet, there was a large deformation of both droplets before the coalescence and the energy dissipation was also large. The coalescence happened at the time close to the maximum spreading. When the temperature of the impacting droplet increased, the deformation of both droplets became smaller before the coalescence and the coalescence happened at or even before the droplets started to spread. The energy dissipation and loss in the later situation is less than those in the previous case. The rebounding characteristics of the merged droplets were also found to be dependent on the temperature. There is an optimum temperature at which the merged droplets can rebound for more times due to the balance of energy loss and also the interaction of the merged droplets with the underlying superhydrophobic substrate. These findings may help further the fundamental understanding of droplet collision on a superhydrophobic surfaces and also offer an alternative strategy to remove droplets from the underlying surfaces for different industrial applications, including condensation heat transfer in steam power plants and phase-change-based thermal management systems.

The development of a self-cleaning and corrosion resistant superhydrophobic coating for aluminum alloy surfaces that is durable in aggressive conditions has attracted great interest in materials science. In the present study, a superphydrophobic film was fabricated on an AA5052 aluminum alloy surface by the electrodeposition of Ni–Co alloy coating, followed by modification with 6-(N-allyl-1,1,2,2-tetrahydro-perfluorodecyl) amino-1,3,5-triazine-2,4-dithiol monosodium (AF17N). The surface morphology and characteristics of the composite coatings were investigated by means of scanning electron microscopy (SEM), energy dispersive X-ray spectrum (EDS), atomic force microscope (AFM) and contact angle (CA). The corrosion resistance of the coatings was assessed by electrochemical tests. The results showed that the surface exhibited excellent superhydrophobicity and self-cleaning performance with a contact angle maintained at 160° after exposed to the atmosphere for 240 days. Moreover, the superhydrophobic coatings significantly improved the corrosion resistant performance of AA5052 aluminum alloy substrate in 3.5 wt.% NaCl solution.Keywords:superhydrophobic surface;aluminum alloy;corrosion resistance;self-cleaning

The self-cleaning of the superhydrophobic surface (SHS) attracted worldwide interest. However, in most cases it depends on the incoming droplet, which places additional constraints especially in arid area and/or narrow space. Herein, a condensation-induced self-cleaning of dust on the SHS is proposed. First, the SHS are prepared and dust is deposited on the surface, and then the dust removal process is studied on the condensation visualization platform. During condensation, a liquid bridge is initially formed at the contact points between particles on the SHS, which governs dust removal behavior. Specially, three consecutive processes are accounted for the self-cleaning including dust agglomerating, condensate sliding and rolling as the condensate prolongs. As far as the sizes and coverage rate of dust particles are concerned, over 95% of particles can be removed by condensation within 90 min (air temperature 26 ± 0.5 ℃, air humidity 60 ± 5% and cooling-stage temperature 10 ± 0.5 ℃). This study aims to provide a useful, in-depth understanding of dust mitigation by condensation on SHS, which has potential application in PV module and heat exchanger.

In recent years, with the rapid development of the economy and great progress in science and technology, people have become increasingly concerned about their quality of life and physical health. In order to pursue a higher life, various functional and biomimetic textiles have emerged one after another and have been sought after by people. There are many animal and plant surfaces with special wettability in nature, and their unique “micro-nano structures” and low surface energy have attracted extensive attention from researchers. Researchers have prepared various textiles with superhydrophobic features by mimicking these unique structures. This review introduces the typical organisms with superhydrophobicity in nature, using lotus, water strider, and cicada as examples, and describes their morphological features and excellent superhydrophobicity. The theoretical model, commonly used raw materials, and modification technology of superhydrophobic surfaces are analyzed. In addition, the application areas and the current study status of superhydrophobic surfaces for textiles are also summarized. Finally, the development prospects for superhydrophobic textiles based on bionic technology are discussed.Keywords:superhydrophobic surface;biomimetic textiles;lotus leaf;theoretical modeling

Herein, a superhydrophobic surface was designed and fabricated based on the “lotus effect” construction mechanism. The zeolitic imidazolate framework (ZIF-90) micro-nanoparticles were initially synthesized via a one-pot method, combined with long-chain stearic acid (STA), and subsequently embedded in polyvinyl butyral (PVB) to form a superhydrophobic surface at room temperature. The superhydrophobic surface demonstrated mechanical stability and retained its superhydrophobicity with a water contact angle (CA) greater than 150°, even at a wear distance of 400 cm. The composite coating formed by applying this superhydrophobic surface to magnesium (Mg) alloy exhibited a high corrosion potential (Ecorr = −0.86 V) and a low corrosion current density (icorr = 3.66 × 10–12 A·cm–2) compared to the uncoated Mg substrate (Ecorr = −1.53 V, icorr = 1.14 × 10–4 A·cm–2), indicating that the coating effectively enhances the corrosion resistance of the substrate. Notably, the superhydrophobic composite coating demonstrated corrosion resistance durability with a high charge transfer resistance (Rct = 5.12 × 109 Ω·cm2) after 5 days of immersion in 3.5 wt % NaCl aqueous solution. In addition, the as-prepared superhydrophobic surface also displayed excellent performance in self-cleaning and anti-icing. We believe that this work can facilitate the application of ZIFs on superhydrophobic surfaces and provide a new approach for metal corrosion protection.

The preparation of hydrophobic surfaces has been extensively studied, but the reversible responsive hydrophobic surface has received less attention. In this paper, poly(styrene-random-methyl methacrylate-random-acrylic acid) (P(St-r-MMA-r-AA)) was prepared by conventional free radical polymerization, and the filter paper and cotton fabric were immersed in P(St-r-MMA-r-AA) methanol solution to construct a hydrophobic surface. The hydrophobic property, chemical composition and surface morphology of the hydrophobic filter paper and cotton fabric surface were characterized by contact angle, Gibbs free energy, infrared spectroscopy and scanning electron microscopy. The optimum conditions for constructing hydrophobic filter paper and cotton fabric surface were investigated. When the surfaces of hydrophobic filter paper and cotton fabric were treated with methanol, tetrahydrofuran and deionized water respectively, the semihydrophobic-hydrophobic-hydrophilic reversible transformation could be achieved. After ten cycles of experiments, the contact angles under the three solvent stimulations had no significant change, and the hydrophobic properties of the hydrophobic cotton fabric were superior to that of hydrophobic filter paper. The Gibbs free energy calculation of the hydrophobic surface indicated that the change in surface hydrophobic property was due to the inversion between the hydrophobic PS segment, the PMMA segment, and the hydrophilic PAA segment.

This report investigates the impact of droplet temperature on the head-on collision of binary droplets on a superhydrophobic surface. Understanding droplet collision is critical to many fundamental processes and industrial applications. There are many factors, including collision speed, collision angle and droplet composition, that influence the outcome of the collision between binary droplets. This work provides the first experimental study of the influence of droplet temperature on the collision of binary droplets. As the droplet temperature increases, the possibility increases for the two droplets to coalesce after collision. The findings in this study can be extended to collision of droplets under other conditions where control of the droplet temperature is feasible. Such findings will also be beneficial to applications that involve droplet collision, such as in ink-jet printing, steam turbines, engine ignition and spraying cooling.

Superhydrophobic surface (SHS) was fabricated on aluminum via surface roughening by NaClO and surface passivation by hexadecyltrimethoxysilane. The long-term durability for storing the sample in air and the chemical stability for contacting the sample with NaCl solution were investigated. The short-term corrosion resistance for immersing the sample in NaCl solution for 1 h was investigated by potentiodynamic polarization, and the long-term corrosion resistance for immersing the sample in NaCl solution for 7 days was investigated by variation analyses on surface wettability, surface morphology, and surface chemistry. All experimental results suggested that the so-obtained SHS possessed good stability and good corrosion resistance under the testing conditions.

The metallization of glass with high density and fine spacing possesses promising application in advanced package in 5 G. However, the adhesion strength between the copper and the smooth glass is still limited. In this paper, a feasible method is developed to prepare ZnO coating on the glass surface which served as an adhesive layer to provide a good anchors of copper layer by electroless copper plating. The results proved the adhesion strength of the copper layer is as high as 5B by grid adhesion test. Furthermore, diethoxy-methyl-(3, 3, 3-trifluoro-propyl)-silane was used to create an optional hydrophobic surface to accomplish a selective electroless copper plating pattern. The electroless copper plating is non-toxic, convenient, low economic cost and reliable and it is expected to realize promising application in system-in-package in the future.

Superhydrophobic surfaces are considered to be an effective method for anti-icing, but passive anti-icing alone is not as effective as it should be, so it is crucial to develop effective anti-icing techniques. In this study, a photothermal anti-icing structure with multienergy barriers was designed by combining active and passive anti-icing technologies and prepared by a three-step method of laser etching, hydrothermal growth of nanostructures, and chemical modification based on the Cassie–Baxter–Wenzel transition theory. The experimental results show that the static water contact angle of the prepared surface is up to 160°, the sliding angle is less than 3.6°, and the surface temperature is 25 °C higher than that of the original control group over 100 s under standard solar irradiation. The multienergy barrier design greatly prolongs the time of the anti-icing, and the durability test shows that the surface maintains superhydrophobicity even after the abrasion of sandpaper and the impact of sand. This superhydrophobic photothermal coating has great potential for anti-icing and deicing applications.
