Abstract
In a first aspect, an article includes an inorganic substrate and a polymer film layer. The inorganic substrate includes a material including a ceramic, a glass, a glass-ceramic or a mixture thereof. The material includes a metal cation selected from the group consisting of silicon, aluminum, titanium, zirconium, tantalum, niobium and mixtures thereof and oxygen. The polymer film layer includes a polymer including an imide group. From an interface where the inorganic substrate contacts the polymer film layer, a line-profile of a CNO− signal from negative secondary ion mass spectroscopy decreases as it moves away from the interface and into the bulk of the polymer film layer.
