Ice can lead to inconvenience and disasters in human activities, making it a widely concern for researchers to find solutions to prevent icing. Hydrophobic materials have been developed for passive anti-icing with a long time, but without active deicing effect. Recently, researchers have explored hydrophobic photothermal materials with passive anti-icing and active deicing ability, which are limited on cloudy days and the night. Consequently, developing materials with anti-icing/icephobic and deicing capabilities for all-weather use has emerged as an innovative strategy. This paper develops hydrophobic PDMS/Cu-Ni@PET with photo/electric thermal properties to support all-weather anti-icing/icephobic and deicing, which is synthesized using copper-nickel and hydrophobic polydimethylsiloxane (PDMS). The PDMS/Cu-Ni@PET exhibits an outstanding anti-icing performance with a delayed icing time of 1224 s at -10 °C, and achieves a surface equilibrium temperature of 68.9 °C under 1 sunlight intensity, enabling the melting of surface ice particles within 614 ± 118 s. When a voltage is applied to both sides of the fabric, the equilibrium temperature can be reached within 60 s, and attained 158 °C at 6 V, enabling the melting of surface ice within 97 s. It provides a novel approach for developing photo/electric thermal superhydrophobic coatings that can maintain all-weather deicing performance.

The issue of anti-icing and deicing in the low-temperature and high-humidity environment of polar regions has long troubled researchers. The problem cannot be solved perfectly by superhydrophobic coatings alone, and multifunctional composite coatings as well have become a research hotspot. First, hexagonal boron nitride nanosheets were functionalized with polypyrrole (PPy), and then hydrophobic modification was completed by grafting perfluorodecyltriethoxysilane (FAS) to obtain fluorine-modified polypyrrole-functionalized boron nitride (F-BN@PPy). Finally, a photothermal superhydrophobic coating was successfully prepared by using silicone resin as a binder. The coating exhibited excellent photothermal properties, reaching 80 °C in just 3 min under 1 sun irradiation at 25 °C. This can be attributed to the high photothermal conversion efficiency of PPy and the nanostructure of the coating surface, which enhances sunlight utilization. The coating also demonstrated superior hydrophobic properties, reflected by a contact angle of 162° and a sliding angle of 1°, due to the hydrolysis of tetraethyl orthosilicate forming a rough micronanosilica shell and the grafting of the low surface energy FAS. In addition, the performance of the coating maintained good hydrophobic properties by sandpaper abrasion, falling sand impact, bending experiments, or immersion in strong acids and bases for 7 days. This shows that the coating has good mechanical properties and chemical durability. Compared to tinplate, the coating successfully delayed the complete freezing of droplets on its surface at −20 °C by 10 min. On a cooling platform at −40 °C, the F-BN@PPy coating with 1 sun light reached 5.7 °C in only 90 s. The F-BN@PPy photothermal superhydrophobic coating provides an excellent anti-icing/deicing solution for extreme environments.

High durability, low cost, and superior anti-icing and active deicing multifunctional surface coatings, especially in the extreme environment, are highly desired to inhibit and/or eliminate the detriment of icing in many fields, such as automobile, aerospace, and power transmission. Herein, we first report a facile and versatile strategy to prepare novel slippery polyols-infused porous surfaces (SPIPS’s) with the inexpensive polyols as the lubricant liquids. These SPIPS’s are fabricated by a spray-coating approach based on amino-modified magnetic Fe3O4 nanoparticles (MNP@NH2) and amphiphilic P(poly(ethylene glycol) methyl ether methacrylate-co-glycidyl methacrylate) copolymer covalent cross-linked hybrids, followed by infusion with various polyols. The as-prepared surface exhibits excellent antifrosting property, that is, it can greatly postpone frost formation as long as 2700 s at −18 °C. Meanwhile, differential scanning calorimetry results clearly demonstrate that SPIPS’s show a remarkable freezing point depression capacity and the crystallization point of water can be decreased as low as −36.8 °C. The SPIPS also displays an extremely low ice adhesion strength (0.1 kPa) due to its unique surface characteristics. Moreover, outstanding active thermal deicing property is achieved for these slippery surfaces because of intrinsically photothermal effect of magnetic Fe3O4 nanoparticle. Hence, these results indicate that this kind of multifunctional bioinspired slippery surface, with superb stability, good cost effectiveness, and easy fabrication, can be used as a promising candidate for anti-icing and deicing applications.

Solar energy-facilitated materials are promising to solve energy loss problems for anti-icing/deicing applications by conversion clean solar energy to thermal energy. However, the photothermal conversion performance seriously affect by dirt and liquid contaminants. Moreover, melted ice may wet photothermal materials and freeze again. Herein, durable superhydrophobic photothermal coatings were designed by modifying carbon nanotubes with dodecylamine (DDA) and dopamine via Michael addition reaction. Thanks to the photothermal synergistic effect of PDA and CNTs, the surface temperature of obtain coating rapidly rose to 89.8 °C under 1 kW/m 2 . Besides, hierarchical structure and low surface energy alkyl long chain of the coating provided excellent self-cleaning property (CA = 162.5 ± 0.9°), which can avoid the adhesion of contaminants and extend the freezing time of ice for anti-icing. Furthermore, the ice quickly melted and rolled off immediately after irradiation, which avoids refreezing again. Thus, the prepared coating maintained sustainable photothermal conversion for effective deicing performance. Besides, the prepared coating possessed mechanical durability, excellent corrosion protection and even kept self-cleaning ability at 400 °C. More importantly, the coating shows excellent self-healing property toward both mechanical and chemical damage. The outstanding environmental adaptability can greatly extend its lifespan and meet the long-term service conditions.

The accumulation of ice in winter has brought many problems in industrial production and everyday life, and how to prevent icing or remove ice rapidly has aroused great attention from researchers in recent years. In this work, we demonstrated a strategy of using a superhydrophobic photothermal and thermal isolation macroporous xerogel (PMX) to delay icing and remove ice efficiently under faint sunlight irradiation. An oriented macroporous xerogel was prepared by an ice templating method, and multi-walled carbon nanotubes acting as the photothermal genesis component under sunlight irradiation were introduced into the xerogel. After fluorination, the PMX presented a robust water repellency and delayed icing. More importantly, numerous macropores in the PMX matrix acted as the thermal barrier that can restrict heat transmission to surroundings at maximum, which guarantees efficient anti-icing and de-icing in low temperature. Water on the PMX surface can never freeze at −30 °C under 0.25 kW/m2 (“0.25 sun”) sunlight irradiation. The outdoor experiment also has confirmed the availability of PMX in a natural winter environment. The PMX integrated with thermogenesis and thermo-isolation functions provides a new route for highly efficient anti-icing and de-icing.

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.

Ice crystals and snow adhesion can affect the operation and reliability of machines in cold, snowy conditions, so anti-freeze systems are often installed in machines. Commonly used ice protection systems usually place electrothermal and a hydrophobic layer in one layer, or create a hydrophobic layer at top of the electrothermal layer. However, the hydrophobic layer ruptures and there is a risk of a short circuit when water comes into contact with the electrically heated layer. In this paper, a method of using boron nitride film to separate the functional layer is proposed to reduce the risk of short circuit in the electric heating layer. Finally, boron nitride film is successfully used as the intermediate layer to connect the superhydrophobic layer with the electric heating layer, which realizes the passive. The results show that the contact angle of the BN-based composite membrane can reach more than 160°. Under the heating power of 0.54 W/cm 2 , the BN-based composite membrane can reach the steady state temperature of 82.6 °C in 6 min, the deicing efficiency can reach 15.435 kg h −1 m −2 , and the removal of 6 mm thick melting ice takes only 185 s. In addition, after 10 electric heating cycles, the BN-based composite membrane can still maintain a temperature of about 80 °C, indicating that it has good durability. This study is of great significance for practical ice control applications.

Anti-icing and de-icing are vital for infrastructure maintenance. While carbon-based materials with photothermal or electrothermal effects have advanced, they face challenges like environmental dependence, poor resistance, high energy consumption, and complex manufacturing. Here, we developed a scalable, hybrid metamaterial driven by photothermal/electrothermal for all-weather anti-icing/de-icing. Its nanostructured surface delays icing by 360 s at −30°C, breaking records across a wide temperature range. The porous structure enhances light absorption, achieving a delayed icing time of 2500 s at −20°C under one sunlight. The graphene film’s high conductivity allows rapid de-icing with 1.6W power. After 720 h of outdoor exposure, the metamaterial retained a contact angle above 150°, confirming durability. More critically, we have demonstrated that the metamaterial can be manufactured on a large scale, which is essential for improving the economics of the anti-icing/de-icing sector.

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.

The emergence of ice formation and accretion presents significant challenges, catalyzing an urgent need for clean and efficient anti-icing solutions. Solar energy, a powerful and sustainable resource, can be integrated with the micronano-structured superhydrophobic surface to enhance anti-icing and deicing performance through the solar photothermal effect, overcoming the limitations of a traditional superhydrophobic surface. Herein, inspired by bamboo and lotus leaves, a synergetic photothermal anti-icing superhydrophobic surface (PASS) has been developed. This was achieved through nanosecond laser ablation and chemical modification, resulting in a surface with remarkable superhydrophobic low adhesion (water contact angle >167°, rolling angle < 2°). The PASS notably extends the freezing time of water droplets to 1056 s and delays frost formation to 47 min at 60% humidity. Moreover, the surface retains its superhydrophobic properties after enduring several rigorous tests. Additionally, the photothermal conversion efficiency reaches up to 67.31%, and the temperature increases to 95.6 °C under 1.5 sun illumination for 600 s in ambient conditions (Tr = 7 °C). The ice melting time is only 120 s under 1 sun illumination at −15 °C. Consequently, the PASS sample stands as a preeminent strategy for anti-icing and deicing pursuits owing to its exceptional photothermal proficiency, superhydrophobicity, and enduring robustness.

Ethylene glycol (EG) deicer and propylene glycol (PG) deicer were frequently used as the aircraft de-icing fluids in cold region. In this paper, the icing pressure ( I p ), icing volume expansion rate (Δ V P ), freezing point ( T 0 ) and under-cooling ( △T ) of aircraft deicers with different concentrations were investigated, and the above indicators of aircraft deicers were also compared with that of water and NaCl deicers. The results showed that the icing volume expansion of deicers was the direct cause of icing pressure. During the cooling process, values of I p and Δ V P firstly increased sharply, then slowly, and finally became stable. The stabilized values of I p and Δ V P decreased with concentration. The stabilized I p value of EG deicer was slightly higher than that of 3.5% NaCl deicer and far greater than 3.5% PG deicer. Of all the tested deicers, the stabilized Δ V P value of NaCl deicer was the highest and that value of EG deicer was close to that of PG deicer. The results further confirmed the feasibility of using impulse of icing pressure as the indicator to evaluate the freeze-thaw deterioration to concrete.

The inhibition of ice accumulation on surfaces is of great importance in various practical applications and extensive efforts have been made to address this daunting challenge. Among many others, the promising photothermal anti-icing surfaces become ineffective under a nonillumination condition. Herein, a photothermal energy-storage capsule (PESC) by leveraging both the solar-to-thermal conversion and energy-storage capability is proposed for efficient anti-/deicing. Under illumination, the surface temperature can rise to 55 °C, which endows fast droplet evaporation to prevent the subsequent bulk freezing, and the accumulated ice and frost in a low temperature quickly melts and fully evaporates. Importantly, sustainable droplet evaporation can be achieved without illumination which is attributed to the energy storage property of the PESC. This research provides a satisfactory paradigm for surface design in all-weather anti-/deicing applications.
