Superhydrophobic surfaces have been extensively developed as attractive anti-icing/de-icing candidate materials for fiber-reinforced polymer-based composites (FRPCs), thereby often being integrated with electrothermal effect to minimize its energy consumption. However, the structural incoordination between FRPC, superhydrophobic surfaces, and electric heating elements usually leads to high energy loss and low durability. Herein, a wet spraying method was proposed for the fabrication of robust superhydrophobic electrothermal films and that were subsequently endowed to the FRPC surfaces through pressure-assisted integrating molding. Our structural-functional integration strategy does not compromise the molding conditions and key components of FRPC, yielding a >95 % retention of the mechanical strength. Additionally, the electrothermal effect was proven well preserved, thereby enhancing the freezing-delaying effect of 1 + 1>2, reducing ice adhesion strength from 234 kPa to 5.4 kPa, and remaining unchanged superhydrophobicity after 100 cycles of icing/de-icing. The underlying mechanism can be attributed to thermal-governed heat and mass transfer at the interface facilitating synergistic regulation of phase transition and wettability of water/ice. Importantly, the practical value of multi-functionalized FRPC was assessed by icing wind tunnel, confirming the anti-icing effect at 0.3 W/cm 2 and 26 % reduction in de-icing energy consumption. The prepared energy-efficient and highly robust anti-icing/de-icing FRPC should satisfy the growing demands in the aviation and energy fields.

Materials with low ice adhesion and long-lasting anti-icing properties remain an ongoing challenge in ultralow temperature environments (≤−30 °C). This study presents a gel material consisting of a polymer matrix (copolymer of polyurethane and acrylamide) and an anti-icing agent, ethylene glycol (EG), designed for anti-icing applications at ultralow temperatures. The surface shows a prolonged droplet freezing delay of ca. 322 s at −30 °C and frost resistance properties. It also exhibits an ice adhesion strength of 1.1 kPa at −10 °C and 39.8 kPa at −50 °C, resulting from the interaction between EG and water molecules that hinders the crystallization of ice as well as the significant mismatch between elastic gel and ice. In addition, the gel surface exhibits favorable anti-icing durability, with an ice adhesion strength below 20.0 kPa after 25 icing/deicing cycles and mechanical scratch tests. The gel demonstrates remarkable thermal durability, achieved through the H-bonds between the EG and polymer matrix. The H-bonds further enhance the anti-icing performance, thereby remarkably decreasing EG depletion and improving anti-icing durability. Overall, these properties suggest the potential application of this gel material in harsh environments including polar regions.

Icing often brings about severe risks, causing financial losses, compromising personal safety, and damaging facilities, etc. Hence, it is urgent to address icing. In this study, a new approach for the efficient anti/de-icing by the semi-aquatic anole lizards was proposed by developing a photothermal superhydrophobic coating. This coating combined polyaniline (PANI) and polydimethylsiloxane (PDMS), creating a superhydrophobic surface with the efficient photothermal conversion properties. The fabrication process included the deposition of PANI via the in-situ polymerization, followed by the impregnation with PDMS. This coating not only enhanced the fabric light-absorbing ability, but also presented significant hydrophobic properties. It had the surface equilibrium temperature of up to 63.5 °C at the light intensity of 1 sun and contact angle of 147°. The anti-icing tests suggested that the coating extended the condensation time of water droplets from 147 s to 338 s and significantly reduced the ice adhesion strength. Furthermore, the photothermal de-icing performance indicated that both the small ice particles and the large overlying ice layer were all rapidly melted and slid down under light irradiation. The coating also exhibited a strong self-cleaning ability, with contaminants readily removed by the water. Durability tests confirmed that the coating was resistant to the UV light, friction and multiple freeze-thawing cycles, ensuring long-term functionality. These findings provide new scope for the development of green and efficient anti/de-icing coated fabric, especially in greenhouses of the agricultural field.

The coatings with low ice adhesion strength have demonstrated advantageous anti-icing performance. However, the application was limited by the trade-off between ice adhesion strength and durability. In this study, we propose an all-dynamic anti-icing coating system with two-layered structure to address the above issue. First of all, we prepare a polyurea-polyfluoroacrylate block copolymer (PFU-2). The fluoropolymer nanophases and polyurea continuous phases provided icephobicity and mechanical strength, respectively. Further, the dynamic bond exchange enhances chain slippery and fluoropolymer nanophase mobility. In this way, PFU coating exhibited advantageous low ice adhesion strength (∼2 kPa), high durability and self-healability on anti-icing performance. Finally, the all-dynamic coating with polyurea bottom layer/PFU top layer architecture was constructed. In the assistance of dynamic bond, the polyurea bottom layer afforded the elastic behaviour and high self-healing ability. As a result, the freezing of water on PFU-2 surface was reduced by 0.01 g/cm 2 , and the healing ability of the scratch was improved. The PFU top layer afforded low ice adhesion strength while preserving high durability. The combination of multiple functions in the all-dynamic coating made it become a promising anti-icing coating in potential applications.

Condensation freezing inhibition is of great practical importance for anti-icing applications; however, no coatings with this performance have been reported. Here, we report the inhibition of condensation freezing on patterned polyelectrolyte coatings, including polyelectrolyte brush (PB), polyelectrolyte multilayer (PEM), and polyelectrolyte hydrogel (PH) surfaces, benefiting from their feature in regulating ice nucleation and propagation via changing counterions. On the reported surfaces, ice nucleation can be initiated exclusively at the domains with the polyelectrolytes; moreover, spontaneous ice propagation can be achieved atop the patterned polyelectrolyte surface. Consequently, condensed water surrounding the frozen drops on the patterned polyelectrolyte surface evaporates due to the instantaneously released latent heat in the course of ice propagation. Afterward, ice grows specifically on polyelectrolyte surfaces via desublimation as the saturated vapor pressure of ice is smaller than that of condensed water drops. As such, an ice-free region up to 96% of the entire surface area can be accomplished. We demonstrate that various polyelectrolyte coatings can be easily introduced on almost all surfaces, revealing great promise for anti-icing applications.

T he alum-borneol nanoemulsion(ABN), which combines the mineral medicine alum and the botanical medicine borneol, has been applied for approximately 40 years in the clinical treatment of burns, scalds, radiation dermatitis and shingles, and has a good curative effect. However, the current formula and dosage form of ABN pose problems of low borneol content and ease of precipitation, which greatly affects the efficacy of the drug. In this study, polyvinylpyrrolidone(PVP) was selected as a carrier mixed with different proportions of alum and borneol to produce alum-borneol-PVP fibers(ABPF) by electrospinning. The results showed that the stable system with good drug dispersion was 2:3(alum:borneol). The dissolution content of borneol from the ABPF was about 80% in 4 h, which was much higher than that of the alum-borneol liquid(ABL) and ABN. The ABPF membrane showed a more significant inhibitory effect on Staphylococcus aureus than the ABL and ABN. The composite fiber markedly increased the drug content of borneol, which was 800 times of that in ABN. The fiber had a higher solubility than the nanoemulsion in vitro , which is of great importance for the development of new forms for the clinical application of alum and borneol.

Electrothermal anti-/de-icing technology is considered to be an effective means of solving the icing problem on the composite surface of multi-electric/pure-electric vehicle in the future. The electrothermal coating with carbon nanotube concentration gradient was fabricated by the multi-step spraying method, which obviously increased the rate of electric heating by inducing directional heat transfer. The coating temperature remained above 0 ℃ under various low-temperature incoming conditions, when the electric power density as low as 0.4 W/cm 2 . Meanwhile, the concentration gradient coating’s excellent adhesion and electrothermal stability ensured its long service life. Moreover, the surface temperature of the coating on the airfoil model increased rapidly to over 50 ℃ within 180 s at an initial electrical power density of 1.2 W/cm 2 , effectively preventing ice formation on the leading edge for 60 s under −15 °C, 30 m/s flow condition. Under the same conditions, 8.5 mm-thick ice on the leading edge could be swiftly removed within 22 s with initial electrical power density of 1.8 W/cm 2 . This strategy of conductive packing gradient design will provide new insights for advanced electrothermal anti-/de-icing material manufacturing.

The freezing phenomenon poses significant challenges in many fields, causing serious casualties and economic losses. Compared with traditional measures, active/passive coupled anti-deicing technology exhibits greater adaptability and effectiveness in diverse scenarios. Herein, an electrothermal/superhydrophobic coating featuring a sandwich structure was proposed for anti-deicing applications. Benefiting from the hydrophobic modified micro-nanostructure, this superhydrophobic coating boasted remarkable abilities to delay icing and repel water adhesion, rendering it ideal for combating freezing rain. Under a certain electrothermal power density, the coating could be heated quickly and evenly. Furthermore, it has proven to be highly capable of enduring prolonged continuous heating and rigorous high–low-temperature cycling tests, delivering exceptional performance. To evaluate its dynamic anti-icing performance, icing wind tunnel tests were conducted, which demonstrated that the coating can prevent freezing with the coupled electrothermal/superhydrophobic properties, even under harsh icing environments. This work would inspire the design of electrothermal/superhydrophobic anti-deicing coating with a sandwich structure and promote the practical engineering applications.

Borneol synthesis faces challenges from co-generated impurities (isoborneol/camphor) and competing dehydration/dehydrogenation during isomerization. Here, Co/TiO 2 is demonstrated as a selective catalyst for isoborneol-to-borneol isomerization, effectively suppressing structural degradation. Controlled acidity and cobalt dispersion are identified as critical factors: TiO 2 's moderate acidity promotes isomerization, while strongly acidic supports (e.g., Mordenite) favor dehydration to camphene. Reduced cobalt particle size enhances active-site accessibility, lowering activation energy and boosting borneol yield. A one-pot two-step process achieves >62 % borneol content with <0.5 % camphor, meeting ChPC purity standards. This strategy bypasses traditional purification bottlenecks, offering a scalable route for high-purity borneol synthesis. The mechanistic insights into acid strength and metal dispersion provide a framework for rational catalyst design in industrial isomerization applications.

Hypothesis Ice accretion is a challenging issue for various residential activities and industrial facilities. However, most of the current anti/de-icing coatings fail to maintain their properties when subject to frequent mechanical wear , and their limited functionality (either anti-icing or de-icing individually) cannot meet the requirement of all-weather utilization. Experiments Herein, a multifunctional superhydrophobic coating is prepared by compositing ferroferric oxide nanoparticles (Fe 3 O 4 NPs) with fluorinated epoxy resin via an inverse infiltration process. The surface composition, morphology and wettability are systematically characterized using Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDX), laser scanning microscopy and contact angle tensiometer. The anti-icing and de-icing performances are evaluated by investigating the freezing delay and photothermal effect, respectively. Findings This coating shows outstanding water repellency (water contact angle up to 161.0°, sliding angle down to 1.4°) and can maintain superhydrophobicity within 400 cycles of tape peeling, 260 cycles of sandpaper abrasion or 25 cycles of sand impact. Besides, because the hydrophobic nano/micro hierarchical structures tremendously retard the heat transfer, the freezing process of water droplet on this coating can be apparently delayed by up to 35 min as compared to the uncoated substrate. Moreover, owing to the photothermal effect of the Fe 3 O 4 NPs, the coating’s surface temperature can be rapidly increased above 0 °C under infrared irradiation, which facilitates the ice melting on cold surfaces . Our work offers a versatile approach to address the icing problems in diverse weather conditions, which exhibits great prospects in various engineering applications.

We prepared superhydrophobic surfaces (SHS) with various morphologies on 7075 aluminum, demonstrating that the SHS with small nanoscale asperities of ~80 nm yielded the lowest ice adhesion forces of ~80 kPa, due to the lubricating effect of the overcooled water, and the ice menisci caused by the high surface roughness deteriorated the surface’s icephobicity. To overcome this, slippery lubricant-infused porous surfaces (SLIPS) were prepared, only to find that the removal ability of water on SLIPS was not sufficient to represent its anti-icing ability, and the ice-adhesion force on SLIPS exhibited a negative correlation with the surface roughness.

Preparation techniques of functional surfaces by studying the correlations between the macroscopic properties and microscopic morphologies of biological surfaces and by replicating their microstructural features have been widely discussed. However, surfaces with intelligently switched microstructural morphologies, according to the application scenario, have rarely been reported. Herein, laser etching techniques are employed to construct micropillar arrays on a photothermally responsive shape memory polymer (SMP) surface. In situ reversible conversion of surface microstructure morphology is achieved with near-infrared (NIR) light and external forces, further promoting surface wettability conversion. Cycling experiments show that this reversible wettability transition can be repeated many times, demonstrating its applicability as a microdroplet manipulation platform for droplet capture and remote release. By combining the microstructural morphologies and photothermal response properties of the reversible surface transition, the passive anti-icing and active de-icing performance characteristics of different surfaces at various stages are compared by analysing the droplet phase transition processes and variations in ice shear strengths. These functionalized surfaces with NIR light-controlled reversible wettability may allow new possibilities for droplet selection and transfer processes, chemical microreactions and full-process dynamic anti-icing/de-icing applications.
