Abstract
Anti-fouling treatments are applied to polymer substrates for preventing bacterial adhesion. The polymer substrate may comprise a medical device, such as a catheter. The treatment generally comprises a polymer layer graft polymerized to the surface of the polymer substrate. An anti-biofilm agent is contained in the polymer layer or applied to the surface. A polymer over-layer is then applied that encapsulates the anti-biofilm agent. The anti-biofilm agent prevents bacterial adhesion through the polymer over-layer.
