abstract The present work is devoted to the investigation of the stability of thin plasma polymer films of silica-based material, which were deposited on top of polyurethane coil coatings. Microwave plasma polymerization was used with different precursor mixtures in order to produce thin polymer layers. The effects of precursor gas composition and of pressure were analyzed from the standpoint of the immersion stability of the plasma-deposited polymer films. The results we obtained demonstrate a strong dependence of the immersion resistance on the gas precursor composition and pressure. Decrease of the operating pressure and of the oxygen concentration in precursor mixtures leads to the formation of more compact layers with a higher stability. Introduction of a fluorine-containing component in the precursor mixtures also increases the stability of the plasma-deposited polymer coatings.
