| abstract |
One or more aspects of the disclosure are directed to an article comprising a film disposed on a glass substrate that can be reinforced wherein the interface between the film and the glass substrate is modified such that the article has an improved average bending strength, The film has key functional properties for its application. Some key functional properties of the film include optical, electrical and / or mechanical properties. In one or more embodiments, the interface exhibits an effective bonding energy of less than about 4 J / m 2. In some embodiments, the interface is modified by the inclusion of a crack relaxation layer between the glass substrate and the film. |
