“…Liu and her colleagues at Baotashan Paint Company [43] developed a polyurethane coating with remarkable durability, superb anti-static characteristics, effective slip resistance, quick drying, high concentration of solids, and minimal environmental impact, which adheres to the regulations set by the national environmental protection authorities. Chao and colleagues [89] from the China University of Geosciences employed polyurethane and carbon nanotube particles to fabricate a polyurethane superhydrophobic coating. The findings demonstrated that the covering exhibited favorable characteristics in terms of preventing ice formation and enhancing traction.…”

There has been great interest in the research and development of different anti-skid and highly wear-resistant materials that can effectively reduce energy losses and improve efficiency in numerous applications. This article reviews the design, performance, and application of anti-skid and highly wear-resistant coating materials at home and abroad. First, it introduces the structure and mechanism of anti-skid and wear-resistant coatings. The preparation of different anti-slip coatings is mainly accomplished by changing the base material and anti-slip granules as well as the coating method, and the anti-slip performance is determined with the coefficient of friction test. The application mostly encompasses airplane and ocean decks, as well as pedestrian spaces. This review introduces the development status and research progress of metal-based anti-skid coatings and polymer-based anti-skid coatings, which are two groups of pavement. Finally, the challenges and future development directions of this key field are summarized and considered.

“…The inherent ability of these materials to prevent large-scale water accumulation on surfaces fundamentally mitigates freezing risks. Consequently, numerous scholars have explored their application in road anti-icing contexts. − However, a notable challenge arises in the practical implementation of superhydrophobic coatings: their hydrophobicity tends to decline under prolonged vehicular rolling. This issue manifests in two primary ways: first, vehicular rolling can compromise the micronanostructures of the coating, substantially diminishing its hydrophobicity; second, intense vehicular loads can cause the superhydrophobic material to disintegrate, leading to a complete loss of hydrophobic properties.…”

Superhydrophobic surfaces exhibit considerable potential in road anti-icing applications due to their unique water-repellent properties. However, the nanorough structure of superhydrophobic coatings is highly susceptible to degradation under wheel rolling in practical applications. To maintain effective hydrophobicity under prolonged exposure to wheel rolling, a multilayer superhydrophobic anti-icing coating was developed. This coating utilizes antifreeze protein (AFP)-modified emulsified asphalt as the substrate with carbon nanotubes (CNTs) and silicon carbide (SiC) as surface coatings.Experimental results indicate that the inclusion of AFP enhances the viscosity of the emulsified asphalt, thereby stabilizing the nanorough structure of the coating. Even after 100 cycles of sandpaper grinding and 500 wheel rolls, the coating maintains robust hydrophobic properties. Moreover, when the coating is worn away by long-term high-strength loads, the exposed AFP-modified emulsified asphalt layer continues to exhibit effective anti-icing capabilities, significantly prolonging the complete freezing time of water droplets on its surface. Additionally, the incorporation of CNTs and SiC enhances the photothermal conversion performance, further improving the anti-icing efficiency of the coating under light irradiation. Overall, this coating shows promise for application in road anti-icing strategies.
