A method for creating a functional coating on a substrate in vacuum from a deposited monomer material in absence of oxygen and/or radiation from a radiation source. The substrate may be preliminarily activated with inert gas to form an activated layer thereon. The method may include depositing a fluorine containing monomer having a first CF.sub.3:CF.sub.2 ratio, and forming, on the substrate, the self-assembled polymer coating that has a second CF.sub.3:CF.sub.2 ratio, where the first and second CF.sub.3:CF.sub.2 ratios are equal.

The present invention concerns a method for at least partially preventing discolouration of a substrate by a plasma coating process, by diffusing a plasma prior to and/or during depositing of said plasma on said substrate to form a coating. The present invention also concerns a plasma coating apparatus comprising a plasma diffuser for homogenizing a plasma density nearby a substrate to be coated.
