<p>The method involves producing a reactive gas flow of the cold plasma type by the action of a continuous, alternating or pulsed electric field having a frequency below 500 kHz, ranging in particular from 0 Hz to 100kHz, on a gas atmosphere made up in part or in its entirety from a hydrocarbon component, consisting of one or more C1 to C7 hydrocarbons, particularly methane, the said gas atmosphere being maintained at a pressure of between 1Pa and 60Pa. The shaped object is maintained below its softening point and kept in contact with the reactive gas flow for a sufficient time to allow deposition on its surface of a film between 10 nm and 1500 nm thick derived from the hydrocarbon component. The coated object has durable antistatic properties.</p> |
