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.
