Jet plasma process and apparatus for deposition of coatings and the coatings thereof
First Claim
1. A method for the formation of an organic coating on a substrate comprising:
- 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 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.
