Abstract (en)

[origin: FR2880027A1] Treatment of a polymer article (A) (to deposit a barrier coating on at least one of its faces), comprises the formation of discharge plasma in a precursor gas of 1,1,1,2-tetrafluoroethane or pentafluoroethane. An independent claim is also included for a device (for treating polymeric article (A)), comprises a metallic cylindrical chamber connected to a microwave emission device to emit 2450 MHz, where the establishment of a differential pressure between the internal volume and the external volume of the container occurs, so that the external pressure is higher than internal pressure and the plasma depositing is done on the internal wall of the container.
