A novel superhydrophobic coating composed of soft polydimethylsiloxane microspheres and stiff SiO2 nanoparticles was developed and prepared. This superhydrophobic coating showed excellent superhydrophobicity with a large water contact angle of 171.3° and also exhibited good anti-icing performance and ultralow icing adhesion of 1.53 kPa. Furthermore, the superhydrophobic coating displayed good icing/deicing cycle stability, in which the icing adhesion was still less than 10.0 kPa after 25 cycles. This excellent comprehensive performance is attributed to stress-localization between ice and the surface, resulting from the synergistic effect of soft and stiff particles. This work thus opens a new avenue to simultaneously optimize the anti-icing and icephobic performance of a superhydrophobic surface for various applications.

The anti/de-icing methods are mainly divided into two types: active method and passive method. The passive method generally adopts three ideas: reducing water contact, inhibiting water icing and reducing ice adhesion. Silica aerogels, which have adjustable surface wettability, thermal conductivity and porosity, would be designed to satisfy the requirement for passive anti/de-icing methods. In this work, the organic–inorganic hybrid aerogels based on organosilicon were facilely prepared in a sol–gel procedure, which showed hydrophobic and elastic properties. It could be seen that the thermal insulation effect originating from aerogel-like porous network endowed the efficient anti-icing property. Moreover, the lowest ice adhesion strengths of the above silica aerogels and the related oil-based lubricant-filled aerogels were 7.1 kPa and 5 kPa, respectively, which belonged to the icephobic surface. Besides, the ice adhesion strength only increased to 15.6 kPa after 30 icing–deicing cycles, showing that hydrophobic and elastic silica aerogels had efficient deicing durability.

Passive anti-icing and active deicing have been combined to improve the anti-icing performance of substrate surface in recent years. Some researchers have prepared active deicing coatings by inducing particles with photothermal or magnetic thermal properties. However, the thermogenesis of these coatings can weaken due to loss of particles. In this work, we first take advantage of the photothermal properties of iodine in deicing process, using polymer substrate doped with iodine by heating to endow the substrate with a photothermal property. Superhydrophobic SiO 2 /SiC coatings with passive anti-icing properties were fabricated on the iodine-doped substrate by a simple spray coating method. The prepared surface of samples can warm up to melt the ice under the irradiation of near infrared light and possesses excellent water repellency with a contact angle up to 162°. The results of 3D profile and microstructure observed via scanning electron microscopy demonstrate that the coatings combined with microscale SiC and nanoscale SiO 2 form voids that can capture air pockets. The photothermal effect of substrate-iodine was demonstrated as the surface temperature of the coatings rapidly increased to about 200 °C upon 10 s of irradiation. The concept of harnessing the iodine doping substrate to achieve superior photothermal performances in deicing might shed new light on the development of anti-icing materials for various applications.

Icing has been proven to be one of the main factors causing aviation accidents. Therefore, the development of convenient and intelligent icing detection technology for airplanes in high-cold areas before takeoff is of great significance to ensure its flight safety. Herein, a novel B-based phosphorescent material (h-PA/BA) was simply fabricated by heat treatment of boric acid (BA) and phenylboric acid (PA) precursors. The obtained h-PA/BA emits blue fluorescence (FL) and green phosphorescence (PL) with an observable time for 15 s (PL lifetime 1.203 s). More interestingly, the h-PA/BA can be dispersed well in aqueous solution with quenched PL, but a stronger PL can then be regenerated due to the phase transition from solution to solid (icing) by inhibiting the non-radiative process. The mechanism of PL generation-quenching-recovery for h-PA/BA under different states is studied in detail. By introducing h-PA/BA into commercial deicing liquid (DL), the novel DL developed with an ice warning function (i-DL) can successfully determine whether the airplane is icing according to the changes in FL and PL. This work opens the door to developing novel specific PL materials, which can expand their applications in airplane safety based on the phase-transition-induced phosphorescence during icing.

Superhydrophobic coatings are commonly used to prevent ice formation and adhesion. However, they often lack durability and can be easily damaged. Herein, a coating that can restore the superhydrophobic properties is prepared. By incorporating hydrophobic SiO 2 nanoparticles in silicone coating, a Cassie-Baxter infiltrating surface structure is formed that endows the coating with superhydrophobicity. Then, mesoporous polydopamine nanospheres loaded with perfluorodecyltrimethoxysilane (FAS@MPDA) are added into the coating to realize photothermal self-healing of the coating superhydrophobic property. The results show that the water contact angles can reach up to 155.5°, and the rolling angles can meet as low as 1.9°. The coating can maintain superhydrophobicity even after undergoing 10 self-healing cycles, and also presents a remarkable photothermal effect with temperature of 59 °C under a single solar intensity. The anti-icing test shows that water droplet freezing time is significantly prolonged (654 s), and the ice adhesion strength can reach as low as 10.4 kPa. Moreover, the coating also demonstrates excellent environmental durability in complex environments such as acidic, alkaline, high and low temperatures, erosion and friction. Due to its efficient self-healing performance, exceptional anti-icing capabilities and excellent environmental durability, the prepared coating holds significant potential for extensive applications.

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 accumulation of ice on surfaces can cause numerous safety issues and inconveniences to human life, so there is an urgent need for a simple and effective anti-icing/de-icing solution. In this work, photothermal superhydrophobic foam iron surfaces with multilevel micro-nano-structures were prepared using a combination of chemical etching and surface modification methods. At −15 °C, the photothermal superhydrophobic surface can delay the freezing time of the droplet from 221 s on the original surface to 1220 s. The surface exhibits a favorable photothermal effect, with the temperature rising to 55.8 °C in 240 s when exposed to outdoor sunlight. Furthermore, ice can be rapidly melted in 251 s when illuminated with 0.2 W/cm 2 . The superhydrophobic photothermal surface also exhibits excellent mechanical stability, retaining its superhydrophobicity following sandpaper abrasion cycles and water flow impact experiments. It is noteworthy that the superhydrophobic photothermal surface exhibits enhanced electrochemical anti-corrosion performance relative to the original surface. These findings substantiate the assertion that the prepared photothermal superhydrophobic iron foam surface not only demonstrates effective anti-icing and de-icing capabilities, but also exhibits superior mechanical durability and chemical stability. The straightforward, efficient, and low-cost approach for the synthesis of photothermal superhydrophobic coatings holds considerable promise for potential applications.

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.

Icing pressure testing was conducted to investigate the icing pressure ( I p ) of chloride-based deicers and discuss the relation between I p and the freeze-thaw deterioration of concrete induced by chloride deicers. During the icing pressure test, when the solution transformed from the liquid to the solid phase, undercooling occurred, and the heat of the liquid-solid phase transformation was released. The I p of chloride deicers and water reached a plateau near −30 °C. The stable I p value of water was the highest of that of the chloride solutions followed by that of 3.5% NaCl; the I p of 3.5% CaCl 2 was slightly higher than that of 3.5% MgCl 2 . The concept of the I p cumulative effect with time ( S ) was first proposed to determine the freeze-thaw destruction induced by chloride-based deicers. The durable life of the concrete exposed to chloride-based deicers decreased with the S of the deicers, and the mass loss of the concrete increased with the S of the deicers.

Icing accretion on the surface of an aircraft not only increases the weight but also causes changes in the surface shape, so there is an urgent need for anti-icing/deicing without shutdown. Here, a graphene-based film with light weight, super-hydrophobicity, high electric heat, and durability, which has both anti-icing properties and electrothermal deicing capability, is proposed. The film is prepared with 1 H ,1 H ,2 H ,2 H -perfluorodecyltrichlorosilane (FDTS)-modified SiO 2 /rGO wrinkles, and it has a micro-nanoscale hierarchical structure. Moreover, the superhydrophobic properties of the film can be controlled by adjusting the wrinkle size. Because of its good water repellency, the film can prevent and delay the freezing of water droplets at low temperatures. At −10 °C, compared to a smooth rGO film, the icing time of 10 µL supercooled water droplet on the micro-nanoscale hierarchical structured film can be delayed by ≈8.3 times, and the ice adhension decreases greatly. In addition, the film exhibits high-efficiency electrothermal properties. At −10 °C, under a low voltage of 15 V, the film can be heated rapidly to achieve rapid deicing and defrosting. The graphene-based micro-nanoscale hierarchical structure shows great potential in the field of sky anti-icing and real-time deicing.

Superhydrophobic surfaces show attractive anti-icing properties. However, it remains a challenge for them to achieve icephobicity and ultralow ice adhesion in a humid environment, which is fundamentally attributed to the icing behavior on their hierarchical textures. Here, we address the issue by integrating a superhydrophobic copper mesh with an intelligent organogel that can secrete antifreezing agent autonomously in response to temperature. The antifreezing agent is composed of ethylene glycol and water. By autonomously secreting the antifreezing agent at subzero temperatures, the hybrid surface effectively inhibits the frosting process on the hierarchical texture of the superhydrophobic mesh. Consequently, the surface not only exhibits excellent antifrosting properties in a humid atmosphere but also repeatedly removes the ice deposited spontaneously due to ultralow ice adhesion (8 Pa). This integration of intelligent organogel paves a new and promising avenue to design superhydrophobic surfaces with excellent icephobic properties.

Superhydrophobic surfaces coupling with photothermal effect, as a passive solution independent of external energy input, have shown promising perspectives for anti-icing and deicing . However, most hydrophobic photothermal materials are costly and require complicated fabrication processes, which limit their development in large-scale applications. Here, a facile method is proposed to fabricate superhydrophobic photothermal anti-icing coating using commercially available biochar (BC) and low-cost titanium nitride (TiN) nanoparticles . The coating displays superior photothermal conversion and anti-icing performance, benefiting from the micro-nano hierarchical structure's light trapping effect and high surface roughness . Meanwhile, the coating shows an extra-long anti-icing time of ∼831s for water droplets, which is ∼17 times longer than pure BC coating. The covering frost and ice can be melted into droplets under the illumination of sunlight and roll off rapidly, leaving a dry surface. The superhydrophobic photothermal coating may promote the development of anti-icing and deicing surfaces in outdoor applications.
