  • Patent number: 11286392
    Abstract: The invention relates to a solid plasma polymer body, especially a plasma polymer layer, which has an exceptionally high modulus of elasticity at a given C/O ratio. It further relates to a solid body comprising a substrate and, applied to this substrate, a plasma polymer layer of the invention.
    Type: Grant
    Filed: September 25, 2014
    Date of Patent: March 29, 2022
    Assignee: Fraunhofer-Gesellschaft Zur Förderung Der Angewandten Forschung E.V.
    Inventors: Klaus-Dieter Vissing, Matthias Ott, Gregor Grassl, Wolfgang Hielscher
  • Patent number: 10259201
    Abstract: The invention relates to a composite comprising (i) a plastics component or (ii) a semifinished plastics product with a protective layer system, where the protective layer system comprises a plastics film and an organosilicon plasma polymer layer, the organosilicon plasma polymer layer is arranged between the (i) plastics component or the (ii) semifinished plastics product and the plastics film and, after the hardening of the (i) plastics component or of the (ii) semifinished plastics product, the organosilicon plasma polymer layer adheres more securely to the plastics film than to the (i) plastics component or the (ii) semifinished plastics product.

  • Patent number: 10100165
    Abstract: Siliconized release film for the production of polymer moldings from fiber composites using a mold, which comprises a support film which is capable of vacuum deep drawing at room temperature and a coating which can be applied in liquid form and consists, optionally after removal of any solvent, of more than 90 atom % of silicon, carbon and/or oxygen, more than 45 atom % of carbon and more than 20 atom % of silicon, in each case based on the total coating and measured by XPS, characterized in that the coating has been crosslinked by means of condensation reactions, addition reactions or radiation.
