1. A vessel comprising:
a thermoplastic wall having an interior surface enclosing a lumen;
a barrier coating positioned between the interior surface of the thermoplastic wall and the lumen, and supported by the thermoplastic wall, the barrier coating being effective to reduce the ingress of atmospheric gas into the lumen compared to a vessel without the barrier coating; and
a passivation or pH protective coating positioned between the barrier coating and the lumen, and supported by the thermoplastic wall, the passivation or pH protective coating being effective to decrease the dissolution rate of the barrier coating;
in which the passivation or pH protective coating comprises SiOxCy, in which x is between 0.5 and 2.4 and y is between 0.6 and 3, and
an FTIR absorbance spectrum of the passivation or pH protective coating has a ratio greater than 0.75 between:
the maximum amplitude of the Si—O—Si symmetrical stretch peak between about 1000 and 1040 cm-1, and
the maximum amplitude of the Si—O—Si assymmetric stretch peak between about 1060 and about 1100 cm-1.
