Beschreibung
Zusammenfassung:	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 (CFx)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 C2F6 and H2; C2F6 and C2F4; CF4 and H2; CF4 and C2F4; or of C2F4. 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.
