1. A method for depositing a polymeric material onto a substrate, the method comprising introducing a monomeric material in a gaseous state into a plasma deposition chamber in which a plasma zone has a volume of at least 0.5 m3, igniting a glow discharge within said chamber, and applying a voltage as a pulsed field, at a power of from 0.001 to 500 w/m3 for a sufficient period of time to allow a polymeric layer to form on the surface of the substrate.
