Abstract
One aspect of the present invention relates to a method of fabricating a low friction, wear resistant, polydopamine/polytetrafluoroethylene layered film. In one embodiment, the method comprises the deposition of a polydopamine film on a stainless steel substrate through an oxidative polymerization process, the deposition of a polytetrafluoroethylene nanoparticle film on top of the polydopamine film, and heat treating the layered film to remove moisture and fuse the particles together.
