Abstract

A vessel has a lumen defined at least in part by a wall. The wall has an interior surface facing the lumen, an outer surface, and a plasma-enhanced chemical vapor deposition (PECVD) coating set supported by the wall. The PECVD coating set comprises a water barrier coating or layer having a water contact angle from 80 to 180 degrees, applied using a precursor comprising at least one of a saturated or unsaturated fluorocarbon precursor having from 1 to 6 carbon atoms and a saturated or unsaturated hydrocarbon having from 1 to 6 carbon atoms. Optionally, the coating set includes an SiOx gas barrier coating or layer from 2 to 1000 nm thick, in which x is from 1.5 to 2.9 as measured by x-ray photoelectron spectroscopy (XPS), and optionally other related coatings.

First claim

What is claimed:

1. A vessel having a lumen defined at least in part by a wall, the wall having an interior surface facing the lumen, an outer surface, and a plasma-enhanced chemical vapor deposition (PECVD) coating set supported by the wall, the PECVD coating set comprising:
a water barrier coating or layer having a water contact angle from 80 to 180 degrees, optionally from larger than 80 degrees to less than 180 degrees, optionally from 90 degrees to 160 degrees, optionally from 100 degrees to 150 degrees, optionally from 110 degrees to 150 degrees, applied using a water barrier coating or layer precursor comprising at least one of a saturated or unsaturated, linear or cyclic aliphatic fluorocarbon precursor having from 1 to 10, optionally 1 to 6, optionally 2 to 6 carbon atoms and from 4 to 20 fluorine atoms per molecule, optionally hexafluoropropylene (C 3 F 6 ), octafluorocyclobutane (C 4 F 8 ), tetrafluoroethylene (C 2 F 4 ), hexafluoroethane (C 2 F 6 ), hexafluoropropylene (C 3 F 6 ), octafluorocyclobutane (C 4 F 8 ), perfluorohexane (C 6 F 14 ), perfluoro-2-methyl-2-pentene (C 6 F 12 ); a saturated or unsaturated hydrocarbon having from 1 to 6 carbon atoms; a saturated or unsaturated hydrofluorocarbon having from 1 to 6 carbon atoms; or any combination thereof; and
a gas barrier coating set including:
an SiO x gas barrier coating or layer from 2 to 1000 nm thick, in which x is from 1.5 to 2.9 as measured by x-ray photoelectron spectroscopy (XPS), the gas barrier coating or layer having an interior surface facing the lumen and an outer surface facing the interior surface of the wall, the gas barrier coating or layer being effective to reduce the ingress of atmospheric gas into the lumen compared to a vessel without a gas barrier coating or layer, and
a pH protective coating or layer comprising SiO x C y or SiN x C y in which x is from about 0.5 to about 2.4 and y is from about 0.6 to about 3 as measured by XPS, the pH protective coating or layer having an interior surface facing the lumen and an outer surface facing the interior surface of the gas barrier coating or layer;
in which the water barrier coating or layer is between the gas barrier coating set and the interior surface of the wall.

2. The vessel of claim 1 , in which the gas barrier coating set further comprises a tie coating or layer comprising SiO x C y or SiN x C y in which x is from about 0.5 to about 2.4 and y is from about 0.6 to about 3 as measured by XPS, the tie coating or layer having an interior surface facing the gas barrier coating or layer and an outer surface facing the water barrier coating or layer.

3. The vessel of claim 1 , in which the water contact angle is larger than that of the same vessel coated with a water barrier coating or layer only or a gas barrier coating set only.

4. The vessel of claim 1 , in which the water barrier coating or layer is applied directly on the wall and the gas barrier coating set is applied on top of the water barrier coating or layer; the gas barrier coating set further comprises a tie coating or layer comprising SiO x C y or SiN x C y in which x is from about 0.5 to about 2.4 and y is from about 0.6 to about 3 as measured by XPS; the tie coating or layer is in direct contact with the water barrier coating or layer; and the SiO x gas barrier coating or layer is in between the tie coating or layer and the pH protective coating or layer.
