Abstract
The invention relates to a method of producing an object having a fluorinated polymer coating free of per- and polyfluorinated acids and salts thereof, wherein the method comprises a step DF of depositing a fluorinated polymer coating on the object by means of plasma polymerization of a fluorinated precursor monomer and a step IG of exposing the object to an inhibiting gas which inhibits the formation of per- and polyfluorinated acids and salts thereof in or on the deposited fluorinated coating. Thereby step IG is carried out after step DF, and from the start of step DF until the end of step IG the object is treated in a substantially oxygen free atmosphere.
