Antibacterial Polymer Based Transparent Coating for Elimination of Staphylococcus Aureus

AbstractA polymer antibacterial surface has been successfully developed. The coating system used silanes as binder and Ag nanoparticles (AgNPs) as antibacterial agent. One hindrance to wide application of the antibacterial coating is the complexity of its deposition process and technique (eg; sputtering, CVD, spin-coating etc). They are expensive, require special training and suitable only for small size sample. In this work, only sponge is required to apply the coating onto the intended surface. Ball-milling and ultrasonication stirring were used to mix the AgNPs and silanes. The surface properties were characterized by FESEM. The antibacterial properties of the coating were tested against Staphylococcus aureus using JISZ 2801 method. This bacteria is known to cause nosocomial infections and have been posing problems in hospital all over the world. The need to provide bacteria-free environment is imminent especially in operation theatre (OT) and intensive care unit (ICU)
