Icing and ice accumulation pose a huge hazard to human daily life and industrial applications, creating a huge demand for anti-icing/deicing surfaces. Superhydrophobic surfaces are potentially icephobic, but they are prone to be self-locked when exposed in the frozing condition of cold and humid environments , which limits their practical application. Here, inspired by the surface of arrow bamboo leaf, a periodic stepped micropapillae superhydrophobic surface (PSPs) with ultralow ice adhesion is prepared via femtosecond laser processing and hydrothermal method . Due to the micro/nano multiscale and stepped structure, the PSPs forms large and stable air cushions that shows excellent anti-icing/deicing capabilities. Under the action of Laplace pressure and stepped structure, microdroplets on the surface tend to form eccentric bouncing, which enhances the self-removal ability of microdroplets. The delayed icing time of PSPs reaches 48 min, 7.4 times that of the bare surface. The ice adhesion of PSPs is reduced to 1.25 kPa, only one-third of the no-stepped micropapillae surface. In addition, PSPs exhibits high delayed icing capacity in the supercooled water impact experiments under high-humidity environments (about 85%RH). This work provides new insights for designing superhydrophobic surfaces with anti-icing and deicing ability, which can further promote the development of anti-icing/deicing for such surfaces.

Ice formation and accretion in outdoor equipment is a serious issue and various organogel materials with lubrication surface layer have been used as ice-phobic materials for its low ice adhesion strength . Here, an intrinsic self-healing organogel based on dynamic polymer network with self-regulated secretion of surface liquid is prepared by adding silicone oil to reversible crosslinked network. The prepared organogels present a faster self-healing process compared to material with no silicone oil that the scratch can be repaired within several hours in scratch test. Liquid secretion phenomenon is observed by recovery of water sliding angle after removing surface oil layer by water impacting, which confirmed the self-regulated secretion of inner liquid. Ice adhesion test shows that the organogel surface has a low ice adhesion strength (14.3 ± 1.6 KPa for PDMS-UI-80) during continuous icing/deicing process. The novel organogels provide a new idea to produce durable ice-phobic material with self-healing and self-regulated secretion properties.

Icing has a severe negative impact on daily life and equipment stability. The slippery liquid-infused porous surface (SLIPS) has been widely studied for icephobicity. However, loss of lubrication leads to the failure of icephobicity. In this work, a self-lubricating photothermal surface (SLPS) based on multiwalled carbon nanotubes (MWNTs) and silicone oil was fabricated by a facile preparation method to realize passive anti-icing/deicing and active deicing simultaneously. SLPS can inhibit frost formation, delay freezing, and reduce ice adhesion strength (τice) under low-light and dark conditions. The τice value of SLPS-5-2 was 5.82 kPa in the absence of light at −20 °C. MWNTs improve the oil locking ability and inhibit oil loss, enhancing durability. The τice value of SLPS-5-2 remained within 20 kPa during 30 icing cycles. Meanwhile, SLPS has the excellent external replenishment capability to recover icephobicity. In addition, SLPS shows excellent photothermal deicing performance to melt frost, droplets, and ice layer quickly. Icing can be removed fast due to the oil layer. Silicone oil enhances the lateral heat transfer, improving the photothermal deicing. This all-in-one integration of the self-lubricating and photothermal effect finally boosts icephobicity compared to the traditional SLIPS or individual photothermal materials toward environmentally compatible and solar-driven icephobicity.

Photothermal materials have emerged as promising candidates for anti-icing applications. Lightweight materials integrating photothermal and superhydrophobic strategies for anti-icing/deicing under extreme conditions remain underexplored. Here, we propose an three-dimensional (3D) network photothermal superhydrophobic aerogels fabricated via VTMS crosslinking and freeze-drying, which is found to drastically improve anti-icing/deicing performance and durability. CFe nanocomposites exhibit magnetic and photothermal properties. CFe x -PLA aerogels own low density (22–32 mg/cm 3 ), superhydrophobicity (146.94°-152.25°), and excellent photothermal effect. The results show the surface temperature of CFe 24 -PLA aerogels increases with the increase of the solar light density, and the maximum temperature can reach 87.53 °C. Under a solar light density, the sun lamp is switched on and off three times in a row, and the maximum temperature of CFe 3 -PLA aerogels could reach and maintain at about 68 °C, presenting excellent photothermal stability. Moreover, The deicing time of CFe-PLA aerogel is shortened from 522 s to 207 s, saving more than 60 % of the deicing time. At −70 °C, the freezing time of 10 μL water droplets on the aerogel surface with CFe is 302.5 s (CFe 3 -PLA), 173.3 s (CFe 6 -PLA), 151.9 s (CFe 12 -PLA), and 107.9 s (CFe 24 -PLA). This work provides a novel and effective method to prepare advanced photothermal aerogels for all weather ourdoor anti-icing applications.

Anti/de-icing coatings to equipment surface are emergingly becoming an essential protection against ice formation and accumulation, especially when they serve in harsh environments. Herein, a novel approach for obtaining photothermal superhydrophobic anti/de-icing FCF-BP/SiO 2 coating with prominent abrasion resistance properties was presented. The fluoroalkyl silane and amino silane were polymerized at elevated temperatures and then closely combined with the resin and curing agent to obtain a film-forming polymer. This polymerization process involved the reaction of amino group on the surface of the modified fluorocarbon resin with the isocyanate group in the curing agent. Then the polypyrrole-coated basalt scales (BP) and SiO 2 NPs were employed to the modified coating system to construct a wear-resistant microscopic surface structure by the inverse infusion process (IIP). The water contact angle (CA) and the sliding angle (SA) of the tested coating was up to 155° ± 2° and 1.5° ± 0.5°, respectively, delaying the icing time to 656 s and maintaining the ice adhesion strength lower than 20 kPa after several icing-deicing cycles. It was verified that the FCF-BP/SiO 2 coating remained superhydrophobic and exhibited excellent mechanical durability even after 300 times of abrasion with sandpaper and 100 times of tape-peeling. Even at −10 °C, the frost (accumulated at −10 °C for 2 h) or ice cube (0.5 g) on the FCF-BP/SiO 2 coating could be effectively removed by 1.00 Sun within approximately 309 s and 760 s, respectively. This provides potential applications for fabricating functional anti/de-icing materials in some prospective fields including marine or aviation fields.

In recent years, photothermal coatings have attracted researchers much attentions for anti-icing applications. However, the overheating due photothermal effect at midday or in non-icing period is inevitably encountered and results in the speed-up aging of the coatings. Herein, a reversible thermochromic phase-transition heat storage coating (TCHSC) containing thermochromic microcapsules is designed to adjust photothermal efficiency by discoloration during non-icing period. In cold surroundings, the coating surface shows black color and presents a high photothermal efficiency, which can transform solar energy into heat for anti-icing and de-icing effectively. Yet, the color of coating turns to white spontaneously in hot surroundings with a low photothermal generation efficiency, which avoids the overheating of coating. Besides, discoloration is caused by forming unconjuncted structure in thermochromic dye, and meanwhile the heat is stored during phase transition process of dye, which helps to adjust the temperature rising and cooling rate of coating and contributes to de/anti-icing. What’s more, discoloration temperature of thermochromic capsules can be tuned by adjusting the melting point of dye in thermochromic capsules. The TCHSC with heat regulation provides a new strategy to tackle the conventional overheating issue of photothermal anti-icing coating in summer or at midday, paving a key step towards its real applications.

The inevitable formation and accumulation of ice on exposed surfaces can have adverse effects on the normal performance of equipment and facilities. Here, we developed a novel strategy to fabricate a coating with superhydrophobicity and photothermal effect. Based on the bottom-up approach, metal-organic framework (MOF) Cu-CAT-1 was grown in situ on a copper (Cu) foil to form nano-whiskers and nanowires, and then coated with octadecyltrichlorosilane (OTS) to obtain OTS@MOF@Cu foil. The coated Cu foil exhibited superhydrophobicity with contact angles up to 155.8°. Such a superhydrophobic foil surface also has good chemical stability in harsh solutions. Furthermore, OTS@MOF@Cu foil exhibited stable icing-delay performance (870 s) and extremely low ice adhesion strength (45.7 kPa). Meanwhile, OTS@MOF@Cu foil possessed rapid photothermal de-icing capability (480 s) and frozen ice droplets can spontaneously fall from its tilted surfaces within 360 s. The frost formation process on the surface of OTS@MOF@Cu foil was significantly delayed, lasting up to 15 min even in cold and high humidity conditions. Molecular dynamic (MD) simulation demonstrated that fluorine-free OTS hydrophobic layer significantly slowed down the ice formation process and reduced the adhesion strengths between the ice layer and the contact surface. This study provides a strategy for designing a material with passive anti-icing and active de-icing performances, which could be extended to the practical applications such as aeriation, electrical and transportation under icing weather conditions.

The rapid freeze–thaw test about ordinary Portland cement concrete (PCC) was performed in the deicers of water, 3.5% ethylene glycol, 3.5% NaCl and 3.5% calcium magnesium acetate (CMA). The ice pressure ( I p ) of deicer was tested, and the concept of the ice pressure impulse ( IPI ) was proposed. A crack density model was employed to describe the freeze–thaw damage process of concrete. Results indicated that the freeze–thaw damage of PCC in CMA deicer was the mildest. The I p value of water was the highest but its IPI value was the lowest. The freeze–thaw microcracks inside concrete was induced by the I p of deicer restrained in concrete pores. The freeze–thaw crack density decreased with the relative depth of specimen. The value of superficial critical crack density was 0.85 ∼ 0.88, when the exterior mortar of concrete began spalling. The value of central critical crack density was 0.32 ∼ 0.34, when the interior freeze–thaw failure of concrete occurred.

Outdoor equipment can suffer from functional failure in winter due to ice accumulation. Although functional materials are widely recognized as promising candidates for anti-icing and de-icing applications, ice inevitably accretes on surfaces at extremely low temperatures and high humidity. If surfaces display reversible superhydrophobic and slippery performance, similar to Lotus leaves and fish skin, it will significantly improve the anti-icing and de-icing performance. This study proposes a novel type of multifunctional coating that could smartly reverse between superhydrophobic and slippery properties on demand. The superhydrophobic coatings with diverse morphologies were obtained by employing different sizes and shapes of nanoparticles . Due to the low adhesion and photothermal properties, the superhydrophobic samples presented good freezing rain prevention and snow-melting performances by outdoor tests in winter. The samples with slippery surfaces were produced by infusing dodecane on the as-prepared superhydrophobic surface. Both the superhydrophobic and slippery surfaces can effectively propel the water droplets, prolong the freezing time and enhance ice removal performance in an extremely cold environment. Therefore, the coated samples with bi-stable states (i.e., superhydrophobic and slippery states) were successfully achieved with the potential to be widely applied under different service environments. This facile strategy will provide the possibility for developing novel materials with smart reversible wettability for anti-icing and de-icing applications.

Ice buildup is a safety hazard for infrastructure, transportation and power lines. However, superhydrophobic anti-icing surfaces as well as traditional mechanical and chemical means can hardly coordinate the high anti-icing efficiency with the durable reusability, energy expenditure or environmental impact. Herein, a sustainable, low-cost and dual-action bilayer bamboo (BLB) sheet is developed by bamboo carbonization and surface hydrogel coating. This BLB laminate consisting of a carbonized bamboo (CB) substrate as photo-absorber and thermal insulator and a gel layer as absorber and heat spreader exhibit highly efficient anti-freezing and de-icing performances by converting solar illumination to heat and ion-specifically inhibiting heterogeneous ice nucleation (HIN). This BLB shows remarkable comprehensive performances of low ice adhesion (τ ice ≈ 0 kPa above −25 °C), good photothermal conversion effectiveness (k T =0.52), great recyclability (switchable dual modes), and enhanced HIN inhibition (T H = −25 °C and t H = 1322 s). We provide the single and synergistic mechanisms governing the photothermal trapping and ion-induced HIN inhibition. We demonstrate the frozen drop melting, ice block self-moving and large-area snow removing efficacy on BLB as a convenient and long-lasting anti-icing biomass-based covering material via laboratory-scale and outdoor experiments.

The icing of transmission conductor seriously threatens the safe operation of power grids. Slippery lubricant-infused porous surface (SLIPS) has shown great potential for anti-icing applications. However, aluminum stranded conductors have complex surfaces, and the current SLIPSs are almost prepared and studied on small flat plates. Herein, the construction of SLIPS on the conductor was realized through anodic oxidation and the anti-icing mechanism of the slippery conductor was studied. Compared to the untreated conductor, the SLIPS-conductor reduces the icing weight by 77% in the glaze icing test and shows very low ice-adhesion strength (7.0 kPa). The excellent anti-icing performance of the slippery conductor is attributed to the droplet impact dynamics, icing delay, and lubricant stability. The dynamic behavior of water droplets is most affected by the complex shape of the conductor surface. Specifically, the impact of the droplet on the conductor surface is asymmetric and the droplet can slide along the depression in low-temperature and high-humidity environments. The stable lubricant of SLIPS increases both the nucleation energy barriers and the heat transfer resistance, which greatly delays the freezing time of droplets. Besides, the nanoporous substrate, the compatibility of the substrate with the lubricant, and the lubricant characteristics contribute to the lubricant stability. This work provides theoretical and experimental guidance on anti-icing strategies for transmission lines.

Although advances in industrial products have brought convenience to our lives, severe weather has increased the safety risks to industrial facilities. Considerable efforts have been made to develop high-performance superhydrophobic anti-icing coatings. Nevertheless, designing a functional coating with both anti-icing properties and self-deicing remains a major challenge. Here, we propose a design strategy to exploit a photothermal superhydrophobic multifunctional coating with excellent anti-icing and deicing properties based on MXene by high-temperature sintering and layer-by-layer coating. Specifically, poly(tetrafluoroethylene) (PTFE) particles provide low surface energy and binding effects. Room-temperature-vulcanized silicone rubber (RTV) enhances the dispersion of the composite particles and the adhesion of the functional coating to a glass substrate. Furthermore, the functional coatings constructed with MXene exhibit outstanding photothermal effects, imparting excellent superhydrophobicity (CA = 160.18°, SA = 1.8°) and efficient photothermal conversion (equilibrium temperature of 109.3 °C). An anti-icing/deicing test is simulated to confirm their efficient anti-icing/deicing performance in practical applications. Overall, the functional coatings designed in this work can be applied in real industrial facilities.
