Abstract
According to at least one aspect of the present invention, a method is provided for forming a polymerized coating on a surface of a substrate. In at least one embodiment, the method comprises providing a plasma gun having an outlet; introducing a pre-polymer molecule into the outlet of the plasma gun to form a number of fragments of the pre-polymer molecule as a plasma output including a direct-spray component and an over-spray component; at least partially isolating the direct-spray component and the over-spray component from each other to respectively obtain an isolated directed-spray component and an isolated over-spray component; and depositing at least a portion of the isolated direct-spray component and the isolated over-spray component onto the surface of the substrate through the outlet to form a base polymerized coating. The plasma gun is optionally operated at atmospheric pressure.
