Abstract: The present invention relates to a coating composition comprising a fluoropolymer and a dopamine derivative. Further, the present invention relates to a process for coating a substrate, comprising the steps of (a) providing a coating composition comprising a fluoropolymer, a dopamine derivative and a solvent; (b) locating the coating composition on a substrate; (c) heating the coated substrate to remove the solvent; and (d) optionally pressing the heated coated substrate against another material surface to bond these to each other. The present coating composition allows the bonding of fluoropolymers through a process that eliminates the need for mechanical keying and hazardous or costly etching processes.

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.
