Abstract: Exemplary flexible coverlenses and the methods of making them are described. The methods may include exposing a surface of a substrate layer to a surface treatment plasma to form a treated surface of the substrate layer. A silicon-containing adhesion layer may be deposited on the treated surface of the substrate layer. A silane-containing adhesion promoter may be incorporated on the silicon-containing adhesion layer. The method may also include forming a hardcoat layer on the silicon-containing adhesion layer, where the silane-containing adhesion promoter is bonded to both the hardcoat layer and the silicon-containing adhesion layer. The exemplary flexible coverlenses made by the present methods are less susceptable to folding fatigue along a bending or folding axis of the coverlens.
