Process for forming an article

Abstract

In a first aspect, a process is described for forming an article, wherein the 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 silicon, aluminum, titanium, zirconium, tantalum, niobium and mixtures thereof, and oxygen. The polymer film layer includes a polymer comprising an imide group. The process includes: (a) applying an amine reagent to a surface of the inorganic substrate, a surface of the polymer film layer, or both; (b) contacting the inorganic substrate with the polymer film layer, such that a surface having an amine reagent is at an interface between the inorganic substrate and the polymer film layer; and (c) applying heat and pressure to the article.
