| abstract |
One or more aspects of the present invention relate to articles comprising a film disposed on a glass substrate that may be strengthened, wherein the interface between the film and the glass substrate is modified such that the article has an improved average flexural strength, while the film retains key functional properties for its application. Some key functional properties of films include optical, electrical and/or mechanical properties. In one or more embodiments, the interface exhibits an effective adhesion energy of less than about 4 J/m . In some embodiments, the interface is modified by including a crack mitigating layer between the glass substrate and the film. |
