| 摘要 |
The invention concerns a method for forming a coating in amorphous carbon material with polymer trend on a substrate of polymer material having the shape of a container to be obtained, such as a bottle or flask, using a plasma with electromagnetic wave excitation, which consists in: introducing into a chamber (2), wherein a high vacuum has been generated, a container blank (18), made of polymer material forming said substrate; injecting into a reaction chamber (2, 18) at least a carbon precursor is gaseous phase under very low pressure, the precursor being selected among the alkane, alkene, alkyne, aromatic compounds or a combination of some of them; generating simultaneously in the reaction chamber a microwave electromagnetic excitation in the UHF (8-12) domain with relatively low power for generating a plasma in temperature conditions which maintain the polymer at a temperature lower than glass transition temperature and which bring about the deposit of a overhydrogenated carbon material with polymer trend. |
