A novel robust, anti-icing, self-cleaning superhydrophobic coating was prepared via a simple, environmentally, friendly and efficient strategy which bond nanoparticles SiO 2 to the polyurethane surface under UV-curing. By controlling the content of nano-silica, a superhydrophobic coating with sliding angle (SA) of 2° and water contact angle (WCA) of 165° was constructed. The coating can be widely applied to various substrates with excellent anti-fouling properties and acid/alkali resistance. Meanwhile, the surface of coating is robust, can maintain superhydrophobic after 750 cycles of friction. In addition, the coating has a good anti-icing property which maintains excellent superhydrophobic after being placed at −10 °C for 100 h. Hence, the coating could be widely used on the surface of transmission lines and wind turbines.

The formation of ice on pavement in winter has a negative impact on road traffic safety . This study improves the anti-icing property of pavements by preparing a superhydrophobic coating for asphalt pavements to ensure traffic safety. Here, a superhydrophobic coating with a hierarchical structure (SCH) was prepared using a resin, nano-silica powder, and other materials. The maximum contact angle was 160.5°. Through scanning electron microscope , confocal 3D microscope, and contact angle tests , it was observed that the SCH has the most complex surface texture ( R a =16.69 μm, R z =65.02 μm) and significant hydrophobic performance (contact angle=160.5°) than the superhydrophobic coating with a single-level structure surface (SCM, SCN). Based on the ice-road shear adhesion theoretical results and ice-road shear test results, it can be concluded that, at a temperature of −10 °C, SCH with a hierarchical surface structure has stronger anti-icing property than SCM and SCN. Pavement friction tests reveal that SCH has a minimal impact on the friction coefficient ( μ =0.643), still meeting the requirements for anti-skid property. Furthermore, accelerated wear tests indicate that SCH maintains sufficient wear resistance on the pavement. After accelerated wear tests, compared with SCM and SCN, it still has the best anti-icing property. SCH exhibits significant hydrophobic, anti-icing, anti-skid, and anti-wear properties, providing reference for the development and implementation of novel anti-icing technologies for pavement.

Ice accumulation is a safety and operational threat in power lines, wind turbines, and transportations. Surfaces having both passive anti-icing and active deicing functionalities are very rare. Here, we report a self-cleaning slippery photothermal trap, which is icephobic passively and deice the surfaces actively by converting sun light to heat at the ice-substrate interface. The photothermal trap consists of three layers: a candle soot layer act as solar radiation absorber, a magnetic iron oxide Fe 3 O 4 nanoparticles layer act as heat spreader for lateral dispersal of sun light, and Room Temperature Vulcanized (RTV) insulation to reduce the transverse heat loss. Upon illumination under microsolar 300, the temperature of the surface increased by 40 °C within 200 s. The heat confinement at the magnetic Fe 3 O 4 nanoparticles layer leads to rapid increase of the surface temperature, ice start to melt and silicone lubricant facilitates the ice removal. The slippery photothermal trap removed the frozen droplet (10 µL) within 40 s upon the illumination of sun light and the frozen droplet was completely converted into water after 7 min illumination of solar light at −20 °C. The developed slippery photothermal trap also melted the fully frost covered layer within 100 s at −20 °C under sunlamp. The average defrosted length (25 mm) was also observed by irradiation of laser light for 45 s. The self-cleaning slippery photothermal coating showed outstanding deicing performance at subzero temperature for long term due to the infusion of silicone oil into the nanostructures and same chemical composition with binder.

Ice accretion caused by freezing rain or snowstorms is a common phenomenon in cold climates that seriously threatens the safety and reliability of telecommunication lines and other overhead networks. Various anti-icing strategies have been demonstrated through surface engineering to delay ice formation. However, existing anti-icing surfaces still encounter several challenges; for example, surfaces are prone to ice-pinning formation due to the impact of supercooled droplets, which leads to a loss of anti-icing effectiveness. In this study, a mushroom-like cross-scale surface (MCS) with extreme pressure resistance and superior anti-ice-pinning property was reported. Specifically, the designed MCS, featuring multiscale microfeatures, re-entrant structure, heterogeneous sidewalls, and nanoscale particles, exhibits excellent anti-icing properties. Ice formation was determined to occur through a process involving liquid penetration, condensation, icing, and frost filling. By establishing an anti-ice -pinning model and a bubble column model, the relationship between structural characteristics and anti-icing performance was clarified. The MCS demonstrates excellent static liquid repellency (contact angle >167°) and robust dynamic impact resistance (water impact with Weber number ≥300). Furthermore, it exhibits an ultralow ice adhesion strength of 0.46 kPa. Notably, the ice adhesion strength remains below 5 kPa even after 15 deicing cycles. The anti-ice-pinning mechanism and robust icephobicity induced by the micromorphologies of MCS provide valuable insights for effective anti-icing prospects in telecommunication line surfaces and other areas in the field of information and communication technology.

Recently, slippery liquid-infused porous surfaces (SLIPS) have attracted extensive attention due to their excellent anti-icing performance. However, the unsatisfactory durability resulting from the loss of lubricant hinders its practical application. Here, a micro/nanointegrated lubricant-infused surface combining microcone hole array and TiO 2 porous nanostructure (P-SLIPS) was fabricated, where its inverted pyramid-shaped microgroove can protect the nanoporous structure from being damaged. Experimental results show that with the aid of microcone hole array, the sanding repelling properties of P-SLIPS have dramatically improved with the significantly decreased ice adhesion strength after 7 sanding cycles. In the process of droplet scouring and dynamic icing, the icing phenomenon in P-SLIPS did not occur even after 10 sanding cycles, while this value is 3 sanding cycles in SLIPS. All of these could be attributed to the introduction of microcone array structure, which makes the coating not be completely damaged during the icing/deicing and sanding polishing processes. Thus, the anti-icing durability of the P-SLIPS can be greatly improved.

Fabricating low-cost and high-efficiency oil-water separation superwetting materials for the demand of oil spilling treatment remains a great challenge. Herein, a superwetting aluminosilicate fiber paper decorated by flower-like nickel-cobalt carbonate hydroxide (NiCo-CH) nanostructures was prepared via the hydrothermal method and chemical modification with stearic acid (SA) or 1H, 1H, 2H, 2H-Perfluoroalkyltriethoxysilane (FAS-17). The superhydrophilic multi-layers nanoflowers combing with nanoflakes were uniformly distributed on the surface of aluminosilicate fiber. The superhydrophilic aluminosilicate fiber was then modified by the SA to obtain the superhydrophobic aluminosilicate fiber (SA-NiCo-CH@Al 2 SiO 5 FP). The SA-NiCo-CH@Al 2 SiO 5 FP revealed high separation efficiency (> 95.4%) for both light oils and heavy oils, and high oil flux (417 L m −2 h −1 –71,656 L m −2 h −1 ). Furthermore, the SA-NiCo-CH@Al 2 SiO 5 FP can also remain superhydrophobicity under various harsh conditions, such as dust, sand impact, acid or alkali, and low-temperature environments. This study revealed an inexpensive and simple-fabricated multifunctional superwetting material, which provides promising avenue for future applications in oil-water separation.

Recently, photothermal superhydrophobic energy-storage coatings (PSECs) with anti-icing abilities via latent heat release in the dark environment have drawn attention, yet their heat transfer mechanisms and material design criteria are rarely reported. In this work, inspired by polar bear fur, a biomimetic laminated PSEC, featuring a hair-like photothermal superhydrophobic surface layer and a fat-like energy-storage layer, was designed. PSECs with different phase-change materials have different performances in anti-icing, and a better anti-icing performance occurs when the phase-transition temperature closely aligns with the ambient temperature. Anti-icing tests of PSECs at −20 °C showed that dodecanol-based PSEC-12 delayed the freezing time to 2967.6 s─outperforming tetradecanol (PSEC-14, 2553.0 s) and hexadecanol (PSEC-16, 2246.4 s). Heat transfer analysis revealed that the temperature difference between phase change and ambient temperatures affects the heat loss rate, surface temperature, and anti-icing performance. This study does more than merely present methodologies for the creation of effective anti-/deicing materials; it also provides a thorough analysis of the thermal transfer behavior exhibited by PSECs throughout the anti-/deicing process, which will help design high-performance anti-icing and deicing materials.

Icing on overhead transmission lines could lead to significant power system failures and substantial losses. Although superhydrophobic surfaces had proven effective in preventing icing, the surface structure and function of the most superhydrophobic anti-icing surfaces with low melting efficiency were easily damaged in extreme weather conditions. In this study, robust photothermal superhydrophobic coatings with excellent mechanochemical and icing-melting durability based on the fast mussel-inspired adhesion chemistry were developed. The abundant active functional groups in polydopamine (PDA), including phenolic hydroxyl and amino groups, enabled robust bonding between the aluminum alloy (Al) substrate and the hydrophobic layer via multiple bonding effects. The photothermal superhydrophobic surface (Al@DPDA-FAS) could reach the contact angle (CA) of 158 ± 3° and the sliding angle (SA) of 3°, and showed good photothermal property with temperature of 80.9 ℃ after 10 min of irradiation under 1 sun. Moreover, its delayed icing time significantly extended to 436 s, and the photothermal ice-melting time was shortened to 65 s, demonstrating anti-icing and de-icing performance. Additionally, the excellent durability of Al@DPDA-FAS was confirmed in various assessments, including mechanical abrasion, chemical soaking, cyclic icing/melting. Its surface still had superhydrophobicity after 12 m of sandpaper abrasion, soaking in acid for 18 h, soaking in alkali for 3 days and 40 cycles of icing/melting, respectively. Moreover, the corrosion inhibition efficiency of Al@DPDA-FAS could reach 99.49 % in comparison with the bare Al surface. This work presented a novel approach to develop a robust superhydrophobic coatings with excellent photothermal anti/de-icing property through mussel-inspired adhesion chemistry.

The integration of bio-inspired nanostructured metal-organic frameworks (MOFs) with textiles opens new frontiers for smart wearable systems. This study develops a mechanically robust superhydrophobic AgTCNQ-MOF hybrid fabric via in situ self-assembly, mimicking cactus spines to achieve water contact and sliding angles of 159.2° and 1.8°, respectively. The optimized textile demonstrates multifaceted functionality: 1) Ultrahigh oil-water separation performance (efficiency: 98.4%; flux: 18.0 kL·m −2 ·h −1 ); 2) Anti-icing capacity extending freezing onset from 105 s to 685 s under −20 °C; 3) Full-spectrum UV resistance (UVA: 2.5%, UVB: 2.7%) with 99.8% antimicrobial efficacy; 4) Autonomous self-cleaning via contaminant-removing rolling droplets; and 5) Outstanding mechanical flexibility (6000 cycles) coupled with ultrahigh solar-thermal efficiency (91.5%) enabled by AgTCNQ-derived ultrasmall-bandgap (0.47 eV) engineering, a notable advancement over conventional systems. A covalent interfacial anchoring strategy ensures exceptional durability, maintaining superhydrophobicity after 30 abrasion cycles or 200 h UV exposure. The ultrasmall-bandgap of AgTCNQ uniquely optimizes photon-to-thermal conversion while maintaining multifunctionality, which is a key innovation differentiating this platform. This synergy between bandgap-engineered nanoporosity and textile flexibility enables real-time environmental responsiveness. Such integration bridges nanotechnology and textile engineering to address wearable-environmental challenges, advancing applications in medical wearables, industrial filtration, and adaptive robotics.

Photothermal superhydrophobic surfaces have garnered significant attention for their exceptional anti-icing and photothermal deicing capabilities. However, the shortcomings of stability and fabrication complexity limit their practical application. This work designed and fabricated a SiO 2 /HWCNTs@EP composite coating that combines robust stability, anti-icing/deicing performance, and facile preparation. During fabrication, the SiO 2 and HWCNTs ratio was systematically optimized by evaluating wettability, photothermal conversion capability, and anti-icing/deicing performance. The composite coating in the ratio of SiO 2 /HWCNTs 1:1 exhibited a water CA of 156.7°, demonstrating superhydrophobicity. HWCNTs assemble to form nano-papillary structures on the surface of SiO 2 particles, generating hierarchical micro/nano structures that enable exceptional light absorption. Photothermal testing revealed a maximum temperature increase of 69 °C (reached in 360 s) under one sun intensity. The composite coating demonstrated a prolonged droplet freezing time of 1026 s at −15 °C. Photothermal deicing testing achieved complete ice melting and detachment within 44 s. Notably, the composite coating retained its superhydrophobicity after mechanical abrasion, chemical corrosion, and high-temperature testing, attributed to uniform nanofiller dispersion and dense interactions within the epoxy resin, ensuring exceptional stability. This work provides novel insights for designing stable photothermal superhydrophobic coatings with dual anti-icing/deicing functionality, contributing to the development of energy-efficient ice mitigation technologies.

Frost-resistant and anti-icing polymeric coatings are widely used for various industries for the extremely low temperatures that often appear in winter. Among different icephobic materials, nontoxic fluorine-free polysiloxanes with a low surface energy present tremendous potential to be utilized as passive icephobic coatings. However, conventional polysiloxanes from limited petroleum-based feedstocks potentially lead to serious resource crisis and environmental concerns. In this work, renewable plant oil-based polysiloxanes were prepared and exploited as passive frost-resistant and anti-icing materials. Renewable plant oil-based diene monomers were polymerized with 1,1,3,3-tetramethyldisiloxane through highly efficient hydrosilylation reactions to yield polysiloxanes. The optimized polysiloxane coating is efficient for the removal of the accumulated ice/frost by natural forces such as wind blowing and gravity. The icephobic coating has an ice adhesion strength as low as 84.8 kPa, presenting great potential for efficient anti-icing and frost-resistant applications. The eminent passive anti-icing and frost resistance properties of the renewable plant oil-based polysiloxane coating could be attributed to its combination of low crystallinity and high chain mobility. The development of biomass-based polysiloxanes offers us an efficient route to access high value-added passive frost-resistant and anti-icing coatings.

Then, the slippery liquid infused porous surfaces (SLIPS) of polyimide were prepared from APT-PDMS, 1,2,4,5-cyclohexane tetracarboxylic dianhydride (HPMDA) and 2,2'-bis[4-(4-aminophenoxyphenyl)] propane (BAPP) by two-step method. The composition and structures of products were characterized by Fourier transform infrared spectroscopy (FTIR), the thermal stability of the substrate was studied by thermogravimetric analyzer, the surface morphology and properties of the substrate was observed by scanning electron microscope and Contact angle test. The results show that Slide angle (SA) and stability were the best when the polymer concentration was 30 mg/mL, and the slip angle after oil filling was 3°. Compared with the superhydrophobic surface, the SLIPS own excellent anti-icing and anti-freezing performance, thermal stability, and antibacterial adhesion performance.
