Due to the COVID-19 epidemic issues, the ability to resist to bacterial contamination has become important. Among the various materials, leather has been developed in diverse applications. Especially the demand for synthetic leather is globally increasing because the manufacturing process is simple. In this study, a surface modification was performed by “fluorinated silica nanoparticles” (FSNPs) coating on polyurethane synthetic leather in a simple way and achieve superomniphobic properties which is beneficial for reducing bacterial adhesion. The water contact angle (WCA) and oil contact angle (OCA) of modified leather was θ = 159.4° ± 0.3° and θ = 159.5° ± 0.2° and its anti-biofouling properties are increased to 99.0%. Also, FSNPs-coated leather shows thermal and UV tolerance and self-cleaning properties. We anticipate this coating strategy on healthcare environments can significantly reduce or eliminate potential risks associated with various cross-contamination scenarios.
