Due to the construction of complicated micro-/nanohierarchical structures, designing durable superamphiphobic Al surfaces by a simple, environmentally friendly, and fast method remains a great challenge. In this article, we used a simple and environmentally friendly technique that includes laser marking and water boiling treatment to create triple-scale micro-/nanostructures on 1060 Al surfaces. The as-prepared 1060 Al surfaces revealed excellent superamphiphobicity with low sliding angles, owing to great Cassie state stability after 1H,1H,2H,2H-perfluorodecyltriethoxysilane (FAS-17) modification. The contact angle of the water droplets reaches 160°, and that of peanut oil droplets reaches 155° on this surface. Meanwhile, this superamphiphobic Al surface also possesses excellent self-cleaning ability and oil resistance. Even when entirely immersed in oil sludge, the as-prepared Al surfaces can retain superamphiphobicity. Furthermore, the as-prepared superamphiphobic Al surface demonstrates outstanding chemical stability and endurance in a variety of application environments. In addition, the as-prepared superamphiphobic Al surface offers potential anti-icing and anti-frosting properties. Therefore, the as-prepared superamphiphobic Al surface will be a potential candidate with broad applications in aerospace, construction, and marine industries. Graphical abstract

Superhydrophobic surfaces are susceptible to structural deformation and damage during use, which significantly impacts their long-term stability and performance in anti-/de-icing applications. To address this challenge, a biomimetic superhydrophobic polyurethane film inspired by Xanthium strumarium (PBXS) is proposed. This film not only delivers efficient anti-/de-icing performance but also demonstrates exceptional long-term durability. Even when the surface structure undergoes deformation or complete fracture, it can quickly self-heal under near-infrared light, restoring its original properties. The results show that, due to the superhydrophobic micron spine array and photothermal effect, PBXS can delay droplet freezing at low temperatures (−10 °C, 2052 s) and enable rapid de-icing (1 sun, 187 s). Moreover, by incorporating the shape-memory properties of thermoplastic polyurethane and self-healing capability, PBXS effectively addresses issues related to surface deformation (after ten deformation-healing cycles, PBXS maintains a water contact angle of 157 ± 1° and a rolling angle of 15.4 ± 1°) and material rupture (after ten fracture-healing cycles, PBXS retains a water contact angle of 152 ± 1° and a rolling angle of 16.1 ± 1°). This innovative approach enhances the long-term performance of anti-/de-icing films and shows significant potential for applications in road transportation, power transmission lines, and other anti-/de-icing fields.

Environmentally robust super-repellent and flame-retardant materials satisfying various functional necessities under harsh weather events to provide protections from fouling and burn injuries have proven challenging to attain. Here, a unique four-tier hierarchical macro/micro/nanostructure is designed and constructed by regulating the accretion of multiscale organic–inorganic hybrid building blocks using silica nanoparticles, microsized ammonium polyphosphate, fluorinated alkyl silane and fluorocarbon surfactants, leading to appreciable self-cleaning, antifouling and anti-icing properties in addition to excellent flame retardancy. The fabricated rough surface exhibits super-repellency to a variety of liquids, including synthetic blood, edible oil, hexadecane, concentrated H 2 SO 4 , and even dodecane. The hierarchy of the surface texture is found to be decisive for satisfactory liquid repellency and weather resistance. In addition, the coated fabric presents an enhanced buoyancy which could load 40.2 times its own weight in water and demonstrates a favorable icing delay time of 1168 s. Various stability tests show that the coating maintains a good nonwetting state even under harsh conditions, including mechanical abrasions, repeated washing, chemical corrosion, heat treatment, and strong ultraviolet irradiation. Thus, this work provides a feasible and sustainable strategy for constructing multifunctional protective materials used in advanced protective clothing, infrastructure and transportation facilities.

Superhydrophobic surfaces with micron-nanosized two-tiered structures have huge potential in practical applications. However, the complex preparation process and low-stability of the versatile superhydrophobic surfaces restricted their wide application. Herein, a facile chemical etching process was applied to create a micron-sized rough structure on the 1060 aluminum alloy substrate, and the micron-sized rough structure surface (M-surface) was hydrophobic with a water contact angle of 113.50° ± 2.7°. Then, the M-surface was modified by hydrophobic SiO 2 nanoparticles , and a superhydrophobic micron-nanosized two-tiered structure surface (MNSS-TMES/H-SiO 2 coating) with a water contact angle of 161.20° ± 2.3° was constructed. The as-prepared MNSS-TMES/H-SiO 2 coating can maintain superhydrophobicity after self-cleaning, sand impact, and anti-frosting tests. More importantly, the MNSS-TMES/H-SiO 2 coating exhibited superior anti-icing performance and higher defrosting efficiency. The freezing delay time of a water droplet on the MNSS-TMES/H-SiO 2 coating was prolonged to 4973.87 s at − 15 °C, and the frost layer on the resultant coating was melting speedily and turned into several isolated spherical water droplets in approximately 20 s. Therefore, the prepared durable fluorine-free superhydrophobic MNSS-TMES/H-SiO 2 coating with self-cleaning performance, higher defrosting efficiency, and the ability to delay icing, which has great prospects in practical applications.

Superhydrophobic coatings with high non-wetting properties are widely applied in anti-icing applications. However, the micro-nanostructures on the surfaces of superhydrophobic coatings are fragile under external forces, resulting in reduced durability. Therefore, mechanical strength and durability play a crucial role in the utilization of superhydrophobic materials. In this study, we employed a two-step spraying method to fabricate superhydrophobic FEVE-based coatings with exceptional mechanical durability, utilizing fluorinated TiO 2 nanoparticles and fluorinated Al 2 O 3 microwhiskers as the fillers. The composite coating exhibited commendable non-wetting properties, displaying a contact angle of 164.84° and a sliding angle of 4.3°. On this basis, the stability of coatings was significantly improved due to the interlocking effect of Al 2 O 3 whiskers. After 500 tape peeling cycles, 500 sandpaper abrasion tests, and 50 kg falling sand impact tests, the coatings retained superhydrophobicity, exhibiting excellent durability and application capability. Notably, the ice adhesion strength on the coatings was measured at only 65.4 kPa, while the icing delay time reached 271.8 s at -15 °C. In addition, throughout 500 freezing/melting cycles, statistical analysis revealed that the superhydrophobic coatings exhibited a freezing initiation temperature as low as -17.25 °C.

Copper stearate coating was fabricated on a copper substrate through a simple solution immersion method at room temperature. The surface exhibited grass-like structure, which endowed it with superhydrophobicity and the water contact angle was about 152.3°. Electrochemical measurement revealed that this superhydrophobic surface (SHS) showed better corrosion resistance than bare copper surface and the inhibition efficiency of this SHS was about 95.91%. Moreover, the SHS demonstrated the reduction in adhesion between ice and surface, thus allowing for easy removal of ice. This method may provide a simple way to design SHS with corrosion resistance and anti-icing performance on metal surfaces.

Textile-based flexible sensors with passive anti-icing, active de-icing capabilities, and information transmission are of significant value, especially in low-temperature environments. This study introduced a hierarchically structured textile (PPTZC) composed of zeolitic imidazolate framework-8 (ZIF-8), tannic acid (TA), polypyrrole, and polydimethylsiloxane (PDMS) modified cotton fabric. The innovative design of introducing ZIF-8, followed by etching it with TA to form a hollow structure, enhanced the wearability (breathability, flexibility, lightness, stability, and UV-blocking performance) of the cotton fabric and improved its sensing sensitivity. PPTZC exhibited excellent superhydrophobicity, self-cleaning, anti-icing, photothermal de-icing, and information transmission capabilities. With a light absorbance of 90–95 %, it can rapidly melt ice through photothermal conversion. In a − 20°C environment, the surface temperature of PPTZC can quickly rise from − 20°C to approximately 25°C under 1 sun of irradiation. Both experimental results and COMSOL simulations demonstrated the remarkable anti-icing performance of PPTZC, with the longest ice delay time of 1291.4 s. Additionally, PPTZC can monitor head movements, finger bending, breathing, and pulse in real time, and be used for underwater information transmission and distress alerts. The multifunctional characteristics of PPTZC make it highly promising for use in low-temperature and underwater protective clothing, making it suitable for exploration and research in cold environments.

The development of high-efficiency solar photothermal conversion and storage materials is critical to address the intermittency and randomness of solar energy. In this paper, we prepared magnéli-phase Ti n O 2n-1 (Ti 4 O 7 ) mesoporous hollow microspheres as photothermal materials by employing titanium dioxide and polydopamine as raw materials and using the high-temperature carbothermal reduction method. The Ti 4 O 7 /PCMs with photothermal conversion and energy storage are synthesized by vacuum impregnation of different carbon chain fatty amines (Tetradecylamine (TDA), Hexadecylamine (HDA), and Octadecylamine (ODA)) as PCMs into the Ti 4 O 7 . The Ti 4 O 7 /PCMs exhibit superhydrophobicity and resistance to acid and alkali. The hollow structures help to minimize light reflection by enhancing light scattering and coupling, the photothermal conversion efficiencies of Ti 4 O 7 /TDA, Ti 4 O 7 /HDA, and Ti 4 O 7 /ODA are 89.9 %, 89.5 %, and 90.3 %, respectively, with thermal conductivities of 0.410 W·m −1 ·K −1 , 0.405 W·m −1 ·K −1 , and 0.418 W·m −1 ·K −1 , and latent heats of 155.8 J·g −1 , 162.1 J·g −1 and 151.9 J·g −1 . Meanwhile, the nanoconfinement effect of the Ti 4 O 7 hollow structure effectively solves the leakage problem of fatty amine during the phase change process. The Ti 4 O 7 /PCMs are assembled by spraying, brushing, and molding to meet the needs of multiple working conditions, and their photothermal and electrothermal conversion performances are remarkable in applying anti-/de-icing.

In this work, an anti-icing coating based on superhydrophilic polyzwitterion brushes is reported. Poly(sulfobetaine methacrylate) (PSBMA) brushes were synthesized by surface-initiated atom-transferred radical polymerization to create superhydrophilic films on silicon wafers. The thickness of the PSBMA brushes film increased linearly with the polymerization time, and the film remained superhydrophilic in a nonassociated state when the thickness was less than ∼100 nm. DSC and FTIR analyses revealed that PSBMA contains more nonfreezable bound water than typical polyelectrolytes such as poly(sodium styrenesulfonate) and poly(2-(methacryloyloxy)ethyltrimethylammonium chloride), leading to lower ice adhesion strength than the latter two. At −20 °C, the PSBMA brushes coating demonstrated low ice adhesion strength of 60 kPa, showing a significant reduction in ice adhesion by up to ∼75% compared to uncoated silicon wafer. The optimum PSBMA layer thickness for low ice adhesion was ∼100 nm. These findings suggest that polyzwitterions are excellent candidates for anti-icing coating application.

The fragility of the micro-nano structure makes superhydrophobic coatings highly susceptible to stress, resulting in a decrease in their superhydrophobic and anti-icing performance. In this work, we proposed a new insight to improve durability by incorporating a thin layer of self-healable elastomer with a dynamic network on the micro-nano structure. We constructed superhydrophobic coatings (EP/SiO2/BFVSE) with a three-layered structure of the epoxy resin/silica nanoparticle/silicon elastomer. The silicon elastomer (BFVES) with a B–O dynamic cross-linked network and fluorinated moieties was synthesized by graft polymerization on vinyl silicon oil. The preparation route is facile and convenient for mass production. BFVES has rapid self-healing properties for scratches at room-temperature, underwater and at −18 °C. EP/SiO2/BFVSE preserved apparently higher CAs after being immersed in pH = 1, pH = 13, and NaCl solutions for 96 h as compared with the EP/SiO2 coating. In a water striking environment, the CA of EP/SiO2/BFVSE was slightly decreased to 153°. SEM images further reveal that the recovery of superhydrophobicity and icephobicity is attributed to the self-healing behavior of the boroxine-containing silicon elastomer. The EP/SiO2/BFVSE coating also possesses additional self-healing ability under chemical oxidation. The high durability of the self-healable superhydrophobic coating enables great application potential in aircraft, marine vessels, and outdoor facilities in harsh environments.

To address the limitations of current superhydrophobic materials for oil–water separation, such as the use of non-environmentally friendly raw materials, non-degradability and poor coating durability. This study presents the design of a superhydrophobic fabric that is robust, versatile, and free from fluorine. Inspired by the microstructure of lotus leaf mastoids, the zeolitic imidazolate framework nanoleaves (ZIF-L)/polymethyl methacrylate (PMMA)/polydimethylsiloxane (PDMS) superhydrophobic cotton fabric is prepared by introducing carboxyl groups onto the cotton fabric surface via a diazonium chemical method, followed by in-situ growth of crisscrossed metal–organic frameworks (MOF) structure ZIF-L, and subsequent modification with low surface energy substances PDMS. PMMA was bonded bind to the ZIF-L through hydrogen bonds and van der Waals forces, these interactions significantly improve the resistance to washing and abrasion. The ZIF-L/PMMA/PDMS superhydrophobic cotton fabric exhibits an exceptional water contact angle of 162.2° and a remarkably low sliding angle of only 5.6°. In assessments of durability, the constructed fabric displays exceptional durability, enduring 30 cycles of washing and abrasion without significant degradation of its superhydrophobic properties. It also demonstrates robust anti-fouling and self-cleaning characteristics, alongside outstanding oil–water separation efficiency of over 98 %, and a 95 % efficiency in water-in-oil emulsion separation, coupled with notable reusability. The ZIF-L/PMMA/PDMS superhydrophobic cotton fabric also exhibits superior anti-icing performance as water droplets formed an insulating air layer upon contact with the superhydrophobic surface, thereby reducing heat transfer. Its displays a low ice adhesion strength of 39 kPa at −25 °C, endured over 30 freeze–thaw cycle, and delayed ice formation for more than 120 s at −25 °C. The diminished adhesion strength as a result of the increase of air layer between the water and the superhydrophobic cotton, high surface roughness and PDMS modification, which minimizes ice adhesion.

Developing a superhydrophobic a superhydrophobic anti-icing coating with robust mechanical attributes and chemical resilience is essential for effective anti-icing protection. This study employed fluorine-modified epoxy resin as the resin matrix and Fe 3 O 4 @PPy as the photothermal filler to fabricate an ice-resistant superhydrophobic coating, renowned for its exceptional mechanical endurance and corrosion resistance. With its unique micro-nano structure, the resulting coating exhibited an impressive contact angle (CA) of 158.7° and a minimal sliding angle (SA) of <1°. Even after enduring 260 cycles of sandpaper abrasion and tape peeling tests, the coating retained a CA of 157.8° and 154.2° respectively, demonstrating remarkable mechanical durability. The Fe3O4@PPy coatings exhibit excellent ice resistance with water droplets frozen time prolonging to 524 s at −20 °C. Moreover, when exposed to a light intensity of 100 mW/cm 2 , the coating rapidly heated to 82.4 °C, effectively facilitating de-icing and defrosting, while reducing ice adhesion strength by 88.4 %, underscoring its exceptional anti-icing efficacy. These findings underscore the potential of durable and chemically stable anti-·icing coatings to deliver sustained anti-icing benefits and hold promising practical applications.
