  • Method for Manufacturing a Pecvd Carbon Coated Polymer Article and Article Obtained by Such Method
    Publication number: 20080145651
    Abstract: Method for manufacturing a polymer article having a thin carbon coating formed on at least one of its sides by plasma enhanced chemical vapor deposition, this method including: a first step, corresponding to a time T1 when the treatment pressure is reached in the treatment area, the reactive fluid being injected in the treatment area; a second step, corresponding to a time T2 during which electromagnetic field is applied in the treatment area, characterized in that time T1 is around 1.5 second, time T2 being around 1.2 second, the reactive fluid being a carbon precursor in the gaseous state, its flow being of around 100 sccm.
