Superhydrophobic coatings have attracted a lot of attention due to their excellent self-cleaning and anti-fouling capabilities. However, the preparation processes for several superhydrophobic coatings are intricate and expensive, which restricts their usefulness. In this work, we present a straightforward technique for creating durable superhydrophobic coatings that can be applied to a variety of substrates. The addition of C9 petroleum resin to a styrene-butadiene-styrene (SBS) solution lengthens the SBS backbone and undergoes a cross-linking reaction to form a dense spatial cross-linked structure, improving the storage stability, viscosity, and aging resistance of the SBS. The combined solution functions as a more stable and effective adhesive. Using a two-step spraying technique, the hydrophobic silica (SiO) nanoparticles solution was applied to the surface to create durable nano-superhydrophobic coatings. Additionally, the coatings have excellent mechanical, chemical, and self-cleaning stability. Furthermore, the coatings have wide application prospects in the fields of water-oil separation and corrosion prevention.
超疏水涂层因其出色的自清洁和防污能力而备受关注。然而，几种超疏水涂层的制备过程复杂且昂贵，这限制了它们的实用性。在这项工作中，我们提出了一种简单的技术来制备耐用的超疏水涂层，该涂层可应用于各种基材。将C9石油树脂添加到苯乙烯-丁二烯-苯乙烯（SBS）溶液中可延长SBS主链并发生交联反应，形成致密的空间交联结构，提高SBS的储存稳定性、粘度和耐老化性。该混合溶液用作更稳定有效的粘合剂。采用两步喷涂技术，将疏水性二氧化硅（SiO）纳米颗粒溶液涂覆在表面上，以制备耐用的纳米超疏水涂层。此外，这些涂层具有优异的机械、化学和自清洁稳定性。此外，这些涂层在油水分离和防腐领域具有广阔的应用前景。
