COATED GLASSES WITH HIGH EFFECTIVE FRACTURE TOUGHNESS

Abstract:

Glass-based articles comprise high effective fracture toughness. Glass-based articles comprise: a glass-based substrate comprising opposing first and second surfaces defining a substrate thickness (t.sub.s), a substantially planar central portion, and a perimeter portion; a polymer coating disposed on at least a portion of at least one of the first or the second surfaces; and an effective fracture toughness that is greater than or equal to 1.25 MPa.m.sup.0.5 as measured at room temperature.
