In this study, we developed an epoxy-based superhydrophobic composite coating on Q235 carbon steel substrates using a facile spray-coating technology. The composite coating was fabricated by incorporating epoxy resin and silane-modified Al 2 O 3 nanoparticles as fillers. The resulting coating exhibited superhydrophobic properties, with a water contact angle (CA) of 154.8 ± 0.6° and a sliding angle (SA) of 2.7 ± 0.6°. Anti-corrosion evaluations demonstrated that the superhydrophobic coating provides superior corrosion protection for Q235 carbon steel, as evidenced by a 460 mV positive shift in corrosion potential (E corr ), a four-order-of-magnitude reduction in corrosion current density (I corr ), a four-order-of-magnitude increase in charge transfer resistance (R ct ), and a five-order-of-magnitude enhancement in low-frequency modulus (|Z| 0.01Hz ). Additionally, the coating exhibited remarkable delayed-icing effects, self-cleaning capabilities, and broad substrate applicability, making it a promising candidate for applications in anti-corrosion and anti-icing industries.

Superhydrophobic (SHP) surfaces had promising application in anti-icing field. In this work, ZnO SHP surfaces were prepared on aluminum alloy by radio frequency (RF) magnetron sputtering. The structure, chemical composition, morphology, wettability of the SHP surfaces were investigated by using corresponding methods. The anti-frosting/anti-icing performance of the ZnO SHP surfaces were investigated. Morphology of surfaces showed that sputtering time affected the surface morphology of the ZnO surfaces. When the sputtering time was 15 min, the rough structure exhibited excellent anti-frosting/anti-icing property due to the exceptional superhydrophobicity and self-transfer behavior at subzero temperature, which composed by densely gathered nanoclusters. The freezing of water droplets was delayed for about 2 h, and frosting was delayed for approximately 5 h at the temperature of −10 °C. The SHP surfaces could efficiently enhance the anti-icing property in glaze ice. Meanwhile, the as-prepared ZnO SHP surfaces displayed a low ice-adhesion strength of 12 ± 4.7 kPa. However, the structure with large undulation and pore space reduced the anti-frosting/anti-icing property of the SHP surface. This work provided a direction for the design and preparation of anti-icing surfaces for power transmission lines.

Ice affects many chemical reactions in nature, which greatly influences the atmosphere, climate, and life. However, the exact mechanism of ice in these chemical reactions remains elusive. For example, it is still an open question as to whether ice can act as a catalyst to greatly enhance the reactivity and selectivity, which is essential for the production of some natural compounds in our planet. Here, we discover that ice can lead to high efficiency and stereoselectivity of the [2 + 2] photodimerization of coumarin and its derivatives. The conversion of the [2 + 2] photodimerization of coumarins enhanced by ice is dozens of times higher than that in the unfrozen saturated solution, and the reaction displays a high syn-head-head stereoselectivity (>95%) in comparison with those in the absence of the ice. Note that almost no reaction occurs in the crystal powder and melt of the coumarins, indicating that the role of ice in the photodimerization reaction is not simply due to the usual mechanisms found in the freezing concentration. We further reveal that the reaction rate is found to be proportional to the total area of the ice surface and follows Michaelis–Menten-like kinetics, indicating that the ice surface catalyzes the reaction. Molecular dynamics simulations demonstrate that ice surfaces can induce reactants to form a two-dimensional liquid-crystal-ordered layer with a suitable intermolecular distance and unique side-by-side packing, facilitating stereoselective photodimerization for syn-head-head dimers. These findings give evidence that ice-surface-induced molecular assembly may play an important role in atmospheric heterogeneous photoreaction processes.

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

Surface icing and corrosion considerably reduce the operational safety of offshore wind turbines and can be mitigated through the use of lubricant-infused surfaces, which, however, often suffer from severe performance degradation under real-world conditions and lack long-term durability. Herein, this work prepares polyurea coatings based on a dynamic crosslinked phase-locked network and show that the alternating arrangement of strong and weak hydrogen bonds between the urea units facilitates the capture and storage of the liquid phase (silicone oil), while the affinity and associative interactions between this phase and polydimethylsiloxane segments ensure strong adhesion and integration. The best-performing coating exhibits good dynamic/static anti-icing properties (freezing delay time = 331 s, temperature of first ice nucleatio n = −24.6 °C, ice shear strength = 19.9 ± 3.3 kPa) according to the results of ice crystal growth simulations and wind tunnel tests while showing an exceptional anti-corrosion performance (low-frequency modulus (|Z| 0.01 Hz ) = 4.22 × 10 10 Ω·cm 2 ) and durability. Thus, this study presents a strategy for enhancing the ability of offshore wind turbines to withstand extreme environments and extending their service lifetimes.

The hydrophobic soft coating has low ice adhesion strength and hydrophobic stability in low-temperature and high-humidity environments, which is crucial for preventing ice formation on infrastructure and transportation systems. However, creating mechanically durable hydrophobic soft coatings using simple methods remains challenging. In this study, a high-hardness particle-toughened, self-stratifying organic layer with high photothermal conversion rate was developed to enhance coating durability and ice-repellent performance. By optimizing the ratio of dopamine (DA) and sodium alginate (SA), a hydrophobic photothermal agent (DPSn) with high hardness and a significant light-heat effect was synthesized. A durable, hydrophobic photothermal anti-ice coating (AR/20 %PDMS/x%DPS1) with varying DPS1 amounts was successfully created using a straightforward one-step spray method, utilizing the self-stratification characteristics of acrylic resin (AR) and polydimethylsiloxane (PDMS), along with the toughening effect of DPSn. The fiber cross-linked structure of DPS1 achieved a photothermal conversion rate of 87.5 %. Adding 4 wt% DPS1 increased the surface temperature of the AR/20 %PDMS coating to 96.5 ± 2.4 °C and boosted the coating’s adhesion strength from 6.70 ± 0.3 MPa to 7.23 ± 0.7 MPa. The AR/20 %PDMS/4%DPS1 coating demonstrated excellent anti-/de-icing performance after 60 friction cycles, 60 icing/de-icing cycles, and 132 h of acid-base immersion. Its simple preparation process and durable ice-repellent properties make it highly suitable for practical applications in photothermal hydrophobic soft coatings.

MXene's configuration, whether it is aggregated or dispersed in a monolayer, determines the specific application areas and even greatly influences the intrinsic properties of MXene. However, how to desirably control MXene's configuration is challenging. Here, a simple, additive-free, chemical reaction-free, and scalable strategy to optionally and reversibly regulate MXene's ordered stacking and delamination of MXene aggregates (AM) is reported. Just by controlled freezing of MXene aqueous dispersions, the aggregation percentage, delamination percentage, and interlayer spacing of AM can be finely tuned. Experimental results reveal that the freezing-induced aggregation and delamination effects can be explained by the squeezing action of growing ice grains on the MXene excluded/concentrated between ice grains and the expanding action caused by the ice formation between AM lamellae, respectively. The dominance between them depends on the freezing parameter-influenced ice nucleation sites, numbers, and ice grain sizes. This work not only contributes to the preparation, storage, and practical applications of MXene, but also opens a new and green avenue for controlling materials’ assembly structures.

Superhydrophobic surfaces offer notable advantages, including markedly low water affinity and reduced ice adhesion strength. Nevertheless, their practical utility is impeded by their limited durability and vulnerability to failure in cold and humid environments. In this study, a novel approach for devising an electro-photothermal superhydrophobic (EPS) nanocomposite coating is presented. The findings indicate that the EPS nanocomposite coating exhibits both physical and chemical self-cleaning attributes, showcasing a synergistic interplay of superhydrophobicity, electrothermal, and photothermal characteristics. The superhydrophobic coating delays icing about four times longer than the original coating. At ambient temperatures of −20 °C, the coating stacked with an electro- and photo-thermal performance de-icing layer reduces the de-icing time by about 5 times more than the purely photo-thermal performance de-icing time, and reduces the de-icing time by about 4 times more than the purely electro-thermal de-icing time. Furthermore, the EPS surface demonstrates the capability to sustain temperatures above 0 °C through the photothermal effect on sunny days, utilizing both the electrothermal and photothermal effects on cloudy days, and relying on the electrothermal effect during cold nights. The research introduces a novel method for fabricating functional materials, pertinent to practical anti-icing and de-icing applications.

The rapid movement of electrons during electrical heating produces electromagnetic shielding phenomena (along with an increase in the dielectric constant), which severely hampers the transmission of electromagnetic waves. We propose a patterned structure based on an electrically heated film that enables efficient surface heating and high wave-transmittance. In this paper, the structure exhibits a transmittance greater than 50 % in the 2–18 GHz band and excellent transmittance exceeding 80 % in the 2–8.88 GHz band under vertically incident TM-polarized electromagnetic waves (parallel polarized or vertically polarized wave). The de-icing experiments demonstrated the excellent heating efficiency and fast electrothermal response time of the structure. At a loading power of 4629.6 W/m2, the surface temperature of the structure reached 50.6 °C after 110 s, resulting in the shedding of surface ice. This work proposes a coupling strategy between wave transparency and electro-thermal performance, which is important for promoting the development of integrated structures with stealth/de-icing capabilities.

Superhydrophobic coatings with photo-thermal effects have advantages in anti-/de-icing and self-cleaning. Here, an eco-friendly and low-cost fabrication of superhydrophobic coating was proposed by spraying a water-borne suspension including carbon black and paraffin wax onto substrate-independent surfaces. The a water-borne suspension coated on stain steel plate showed a strong water-repellence, delaying the ice freezing time to 665 s, which is much higher than that of bare stain steel plate (210 s) under the same experimental condition. The ice-melting time was measured as 120 s under a solar irradiation of 0.1 W/cm2, while the control group had no sign of ice-melting during the same time. As a concept of proof, the self-cleaning, anti-corrosion, and oil–water separation were enabled by spraying the water-borne suspension on various substrates, demonstrating its diverse performances. Hence, the water-borne superhydrophibic coating provides an efficient, safe, and sustainable solution for wettability-related applications.

Sodium alginate (SA) aerogels have received extensive attention in environmental modification, energy-related systems, and thermal insulation due to their good processability, nontoxicity, and biodegradability. However, achieving superior mechanical properties remains a significant challenge for SA aerogels as engineering materials. In this work, superstrong SA aerogels are prepared via an effective in situ crosslinking method, consisting of ice-templated preassembly followed by a specially designed dissolution process in mixing GDL/EtOH/H 2 O (δ-glucolactone/ethanol/water) solution. Upon optimization of heat and mass transfer during the ice dissolution process, along with the unique ice template effect, a homogeneous, highly crosslinked, and long-range oriented structure in high-solid fraction SA matrices is obtained. The resultant SA aerogels (248.0 ± 4.4 mg cm −3 ) exhibit an outstanding specific modulus of 1.45 ± 0.15 GPa cm 3 g −1 ( E = 360 ± 32 MPa, σ y = 14.8 ± 0.8 MPa), remarkable energy absorption capability (32.1 ± 4.4 kJ kg −1 ), and considerable thermal insulation performance (0.044 ± 0.007 W m −1 K −1 ). The present strategy paves a way for the fabrication of high-performance SA-based engineering materials with well-oriented microstructures and superior multifunctionality.

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.
