Zusammenfassung: | The invention relates to films, layers, tapes, plates and similar structures of metal or plastic materials coated with thin polyfluorocarbon films and being 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 (CF2)n, wherein x has a value of from 0.3 to 2.0 and are directly obtained on the substrate by plasma polymerisation of gaseous streams of C2F6 and H2, C2F6 and C2F4, CF4 and H2, CF4 and C2F4 or C2F4.
The metal substrate can, for example, be Al, Cu, Fe, tin-coated Fe, Si, noble metals and alloys. The plastic substrates can, for example, be polytetrafluoroethylene, polypropylene, polyethylene, polyphenylene oxide, polycarbonate and neoprene. |
