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.

The present invention provides, in various embodiments, compositions and methods for strengthening glass without heat or chemical processing of the glass itself. The compositions of the present invention are emulsions comprising polymer colloid particles that are functionalized with an organosilicon compound. The polymer colloid particles can fill surface defects in the glass due to their size being smaller than the surface defects, and the functional groups thereon can react with the surface of the glass to anchor the particles in the defects.

A semi-transparent coating material for coating glass or glass ceramics includes at least one sol-gel hybrid-polymer coating system having a hybrid-polymer or inorganic sol-gel-based matrix, and nanoparticles and nanoscale pigments and/or dyes are added to the hybrid-polymer or inorganic sol-gel-based matrix.

A method for preparation of a self-cleaning coating solution is provided. The method comprises mixing an aluminium compound with a solution of an ethanol compound to form a solution. Further, the formed solution is subjected to a first magnetic stirring. After the first magnetic stirring a first transparent solution is formed. Further, a stabilizing agent is added to the first transparent solution of the aluminium compound and the ethanol compound. Subsequent to adding the stabilizing agent a translucent solution is formed. Finally, the formed translucent solution is subjected to a second magnetic stirring for forming a homogeneous second transparent solution. The formed second transparent solution is a coating solution

A glass-ceramic article is provided that includes a surface passivation layer. The passivation layer is an oxide layer and has a thickness of greater than or equal to 20 nm to less than or equal to 200 nm and a RMS surface roughness of less than or equal to 3 nm. The surface passivation layer may be formed with a liquid phase deposition process. The glass-ceramic article may include an easy to clean layer disposed on the surface passivation layer, and the glass-ceramic article may be chemically strengthened. The glass-ceramic article may be used in a consumer electronic product.
