Abstract
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)2-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.
期刊介绍：
ACS Applied Polymer Materials is an interdisciplinary journal publishing original research covering all aspects of engineering, chemistry, physics, and biology relevant to applications of polymers.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates fundamental knowledge in the areas of materials, engineering, physics, bioscience, polymer science and chemistry into important polymer applications. The journal is specifically interested in work that addresses relationships among structure, processing, morphology, chemistry, properties, and function as well as work that provide insights into mechanisms critical to the performance of the polymer for applications.
