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.
