Water Vapor and Oxygen Barrier Properties. The measurements of the water vapor and oxygen permeation were carried out on various polymer films (with and without vapor-deposited layers) and on multilayer laminates ([PET/SiO ]2hybrid polymer). Figure21-18 shows a scanning transmission micrograph of a laminate consisting of PET/SiOj /hybrid polymer.
