    Abstract: Films, layers, tapes, plates, and similar structures of metal or of plastic materials, coated with thin polyfluorocarbon films. These films, tapes, etc., are characterized in that no other materials are interposed; the polyfluorocarbon films are adherent and not porous, and have controlled wettability characteristics. The polyfluorocarbons have the formula (CF.sub.x).sub.n, wherein x is within the range of from 0.3 to 2.0, and are directly obtained on the substrate by the plasma-polymerization of gaseous streams of C.sub.2 F.sub.6 and H.sub.2 ; C.sub.2 F.sub.6 and C.sub.2 F.sub.4 ; CF.sub.4 and H.sub.2 ; CF.sub.4 and C.sub.2 F.sub.4 ; or of C.sub.2 F.sub.4. The metal substrate may be, e.g., Al, Cu, Fe, tin-coated Fe, Si, noble metals and alloys thereof. The substrate of plastic materials may be constituted, e.g., by polytetrafluoroethylene, polypropylene, polyethylene, polyphenyloxide, polycarbonate, and neoprene.
