  • Methods and apparatus for depositing barrier coatings
    Patent number: 5645643
    Abstract: A barrier coating is formed on a polymeric article, such as on the interior of a thermoplastic container. An oxidizing gas is converted to a plasma in a plasma chamber remote from the treatment chamber. The resulting plasma-activated oxidizing species are delivered to the interior of the container. An organosilicon reactant vapor is separately but simultaneously delivered to the interior of the container so that the organosilicon vapor and oxidizing active species mix within the container. An electric qfield is also applied to the container, so that the reaction products are deposited under the influence of the electrical field to form the barrier coating.
    Type: Grant
    Filed: November 21, 1994
    Date of Patent: July 8, 1997
    Assignee: Polar Materials, Inc.
