Due to its excellent anti-water property, superhydrophobic surfaces possess great potential applications in industrial and daily life. However, the durability makes a severe obstacle to their widely used. In this research, we developed a superhydrophobic rubber surface coatings (SHRSCs) with high abrasion resistance and corrosion resistance by embedding silanized silicon dioxide (SiO₂) into the surface of high vinyl polybutadiene rubber (HVPB) matrix based on thiol-ene click chemistry. High-performance SHRSCs were prepared by generating substantial covalent bonds between the sulfhydryl groups of silanized SiO₂ and the side vinyl groups of HVPB under UV light irradiation, as confirmed by swelling. Meanwhile, Scanning electron microscope (SEM)analysis further indicated that HVBR-cladding silanized SiO₂ could form plenty of micro-nanostructures on the surface of HVBR matrix, and significantly reduce the surface energies (SEs). This strategy proposed here suggestes a simple and effective pathway toward high-performance SHRSCs, which promises to be applicatable for surface modification of marine rubber products such as ship bollards and submarine cables.

由于其优异的抗水性能，超疏水表面在工业和日常生活中具有巨大的应用潜力。然而，其耐用性严重阻碍了它们的广泛应用。在这项研究中，我们通过将硅烷化二氧化硅 (SiO ₂ )嵌入基于硫醇-烯点击化学的高乙烯基聚丁二烯橡胶 (HVPB) 基体的表面，开发了一种具有高耐磨性和耐腐蚀性的超疏水橡胶表面涂层 (SHRSCs) 。通过在硅烷化 SiO ₂的巯基之间产生大量共价键制备高性能 SHRSC和 HVPB 在紫外光照射下的侧乙烯基，如溶胀所证实的。同时，扫描电子显微镜（SEM）分析进一步表明，HVBR包覆的硅烷化SiO ₂可以在HVBR基体表面形成大量微纳米结构，并显着降低表面能（SEs）。这里提出的这种策略为高性能 SHRSCs 提供了一种简单有效的途径，有望用于船用护柱和海底电缆等船用橡胶产品的表面改性。
