Inverse vulcanization (IV) enables the production of sustainable polymer from sulfur waste, offering hydrophobic, fluorine-free, and superhydrophobic coatings. However, these materials need adhesion improvements for enhanced durability. This study has developed an epoxy-, fluorine-, and metal-free superhydrophobic coating using the spray-coating of carbon nanofibers (CNFs), silica nanoparticles, and IV polymers on glass. An optimized formula of 28% sulfur, 20 mg/mL CNFs, 25 mg/mL silica, and 80 mg/mL polymer-was established. Zn(DTC)-catalyzed coatings retained superhydrophobicity for 150 tape peeling cycles, up to 250 °C, and 6 h of UV-C exposure, demonstrating a straightforward, eco-friendly approach to durable, versatile superhydrophobic coatings.
逆硫化（IV）能够利用硫磺废料生产可持续聚合物，提供疏水、无氟和超疏水涂层。然而，这些材料需要改善附着力以提高耐久性。本研究通过在玻璃上喷涂碳纳米纤维（CNF）、二氧化硅纳米颗粒和IV聚合物，开发出一种无环氧、无氟和无金属的超疏水涂层。建立了28%硫磺、20mg/mL CNF、25mg/mL二氧化硅和80mg/mL聚合物的优化配方。经Zn（DTC）催化的涂层在150次胶带剥离循环、高达250°C以及6小时的UV-C照射下仍保持超疏水性，展示了一种制备耐用、多功能超疏水涂层的直接且环保的方法。
