Abstract
TaN-(Ag/Au) nanocomposite thin film was deposited on stainless steel (type 316) substrates by cylindrical DC Cosputtering technique. Samples were annealed at 400 °C for different times 3, 5 and 7 minutes. Surface topography, crystalline structure, surface morphology and contact angle measurement of the prepared films were analyzed by using atomic force microscopy (AFM), X-ray diffractometry (XRD) and scanning electron microscopy (SEM) techniques, respectively. Antibacterial activity was measured by using Staphylococcus aurous bacteria at 1, 3 and 6 hours incubation times. The average size of nanoparticles measured less than 40 nm. The average size of particles and contact angle property could be controlled by annealing time and temperature. Results showed that the TaN-(Ag/Au) thin film is hydrophobic (its contact angle is more than 90 degree), so it can decrease the bacteria adhesion to the surface of the samples .
