Abstract
Abstract The present invention provides a method for the formation of an organic coating on a substrate. The method includes: providing a substrate in a vacuum; providing at least one vaporized organic material comprising at least one component from at least one source, wherein the vaporized organic material is capable of condensing in a vacuum of less than about 130 Pa; providing a plasma 10 from at least one source other than the source of the vaporized organic material; directing the vaporized organic material and the plasma toward the substrate; and causing the vaporized organic material to condense and polymerize on the substrate in the presence of the plasma to form an organic coating.
