Patent number: 11884446Abstract: A method for providing a passivation layer or pH protective coating on a substrate surface by PECVD is provided, the method comprising generating a plasma from a gaseous reactant comprising polymerizing gases. The lubricity, passivation, pH protective, hydrophobicity, and/or barrier properties of the passivation layer or pH protective coating are set by setting the ratio of the O2 to the organosilicon precursor in the precursor feed, and/or by setting the electric power used for generating the plasma. In particular, a passivation layer or pH protective coating made by the method is provided. Pharmaceutical packages coated by the method and the use of such packages protecting composition contained in the vessel against mechanical and/or chemical effects of the surface of the package without a passivation layer or pH protective coating material are also provided.Type: GrantFiled: November 16, 2022Date of Patent: January 30, 2024Assignee: SIO2 Medical Products, Inc.Inventors: John T. Felts, Thomas E. Fisk, Robert S. Abrams, John Ferguson, Jonathan R. Freedman, Robert J. Pangborn, Peter J. Sagona, Christopher Weikart

Publication number: 20210330869Abstract: A vessel including a thermoplastic wall enclosing a lumen is disclosed. The wall supports an SiOx composite barrier coating or layer, for which x is from 1.8 to 2.4, between the wall and the lumen. High Resolution X-ray Photoelectron Spectroscopy (XPS) shows the presence of an interface between the composite barrier coating or layer and the wall or substrate. In one aspect, the interface has at least 1 mol. % O3—Si—C covalent bonding, as a proportion of the O3—Si—C covalent bonding plus SiO4 bonding. In another aspect, the interface has an Si 2p chemical shift to lower binding energy (eV), compared to the binding energy of SiO4 bonding. The result is a tightly adherent composite barrier coating or layer having a high degree of adhesion to the substrate under practical use conditions. Methods of applying the composite barrier coating or layer are also disclosed.Type: ApplicationFiled: May 3, 2021Publication date: October 28, 2021Inventors: Christopher Weikart, John T.
