摘要：
An article is described including an article surface and a coating set comprising an optional tie coating or layer, a barrier coating or layer, and a pH protective layer. The respective coatings or layers can be applied by chemical vapor deposition of a polysiloxane or polysilazane precursor in the presence of oxygen. Examples of such an article are a thermoplastic syringe, vial, or blood collection tube with a coated interior portion containing a pharmaceutical preparation or other fluid with a pH of 4 to 8, alternatively 5 to 9. The barrier coating or layer prevents oxygen from penetrating into the thermoplastic syringe, vial, or blood collection tube. The tie coating or layer, if present, and the pH protective coating or layer protect the barrier layer from the contents of the syringe, vial, or blood collection tube.
