| Abstract Scope |
Multi-functional antibacterial coatings are rapidly emerging as a key strategy to mitigate bacterial pathogens in healthcare settings. Amongst them, diamond-like carbon (DLC, i.e. hydrogenated amorphous carbon alloy) as a protective coating is particularly attractive due to its outstanding mechanical and tribological properties combined to chemical inertness and long-term stability. Moreover, the incorporation of AgO nanoparticles have proven to improve the antibacterial activity, whilst synergistically reducing the commonly known internal stress of DLC films. However, one of the main challenges of silver-based antibacterial coatings is to control the release of silver ions throughout an extended period of time. In this sense, additional polymeric top layers can act as rate-limiting barriers to sustain the antibacterial activity duration. Thus, this study presents a novel long-term stable and multi-functional AgO-DLC nanocoating on SS316L with an additional semi-permeable polymeric top layer by means of low-pressure plasma. |
