Globally, the public health domain is increasingly emphasizing need for surfaces that can resist bacterial contamination, as consumption of bacteria-infected substance may cause illnesses. Thus, this study aimed to modify polyurethane (PU) synthetic leather by coating their upper layer with fluorine-functionalized nano-silica particles (FNPs). This simple modification imparted omniphobic characteristics, realizing anti-biofouling and self-cleaning properties. The effectiveness in preventing adhesion was confirmed dip-inoculation method using Escherichia coli O157:H7 Staphylococcus epidermidis. Bacterial evaluated based on counts pour plate directly enumerating from scanning electron microscopy images. attachment bacteria modified FNPs-coated PU surface decreased over 98.2% compared bare surface. We expect developed will significantly reduce or even eliminate potential risks associated various biological cross-contamination scenarios, thereby enhancing hygiene standards.
