Abstract: The issue of foulants spans across multiple sectors, from healthcare to marine and food industries, contributing to reduced material longevity. A promising solution is superamphiphobic coatings; however, their broader applications are hindered by complex fabrication methods, limited substrate adhesion, and chemical instability. To address these issues, this study presents a novel hierarchical superamphiphobic surface coating that integrates fluorinated silicon dioxide and zinc oxide particles. The coating demonstrated exceptional water repellency (≈160°) and oil repellency (≈150°), retaining these properties for 24 h under highly acidic conditions and after mechanical abrasion. The coating’s performance extended across various substrates, including gasotransmitter-loaded surfaces, and a wide range of solvents. Nitric oxide (NO) is a potent antimicrobial agent with established therapeutic applications, and its incorporation into polymers offers a promising strategy for enhancing the functionality of medical devices. Uniquely, this superamphiphobic coating leverages zinc’s ability to catalyze the decomposition of S-nitrosothiols and enhance NO catalysis. This study introduces a multifunctional coating that, as a novel superamphiphobic NO-catalyzing surface, resists fouling. This advancement broadens the potential applications of superamphiphobic materials in both biomedical and industrial settings.
