Apron made of polyurethane is a protective equipment used to prevent cross-contamination of bacteria in the food industry. Antiadhesion of bacteria has been studied a lot. While the use of apron improves hygiene, and is desired for food handling, apron is not problem-free. For instance, when apron used in the fisheries industry, durability of protective equipment can be reduced by salinity. In this study, we report a surface modification achieve including “fluorinated silica nanoparticles” (FSNs) to improve the protective ability against bacterial adhesion of apron surfaces used in salinity water. The bacterial antiadhesive properties of the modified apron were applied with Escherichia. coli. Bacterial repulsion to apron were enumerated by the pour plating method as well as direct counting via scanning electron microscopy. The modified apron assessed its durability against salinity by comparing the water contact angles in the different salinity not only different immersing period.
