Multifunctional Ti₃C₂T_x MXene-Based Composite Coatings with Superhydrophobic Anti-icing and Photothermal Deicing Properties

Abstract

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 antiicing 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.

Versatile Melanin-Like Coatings with Hierarchical Structure toward Personal Thermal Management, Anti-Icing/Deicing, and UV Protection

“…As a common natural phenomenon, ice formation has the risk of causing severe economic and safety problems if not intervened. In recent years, due to the unique structural and functional characteristics of superhydrophobic photothermal coatings, their application to anti-icing and deicing has attracted enormous research interest. ,,, As shown in Figure a, the bare copper plate and the copper plate covered with PDMS@SiO 2 /PDA-fabric are distributed and placed on a semiconductor cooling table and kept at −15 °C. An equal amount of water drops is added to the sample surface to observe the freezing process.…”

Photo-Thermal Superhydrophobic Sponge for Highly Efficient Anti-Icing and De-Icing

“…During warm daytime, enough heat is generated by solar-thermal conversion to keep the temperature of the coating surface above zero to achieve anti-icing and de-icing. On a cloudy day or extremely cold day, the coating can also stay warm to prevent icing owing to photo-thermal and electric-thermal dual effects. , In addition, other photo-thermal materials, such as ferriferrousoxide, , polypyrrole, SiC, TiO 2 /C, Ti3C2T x MXene, and ZnSb, were also used to prepare photo-thermal deicing coatings. For photo- or electric-thermal de-icing materials, reducing the heat loss was first considered due to the close correlation of de-icing efficiency.…”

“…Extreme water repellency keeps their organs from getting wet, even if they are exposed to rain and snow, which provides great inspiration to people to develop functional materials with antifouling, anticorrosion, anti-icing, , self-cleaning, , and oil–water separation properties. These unique features make superhydrophobic coatings have the potential for use in industry and daily life. − …”
