Abstract: A foldable ultrathin glass article includes an ultrathin chemically-tempered foldable glass substrate having a thickness of approximately 100 microns or less and a compressive surface stress of at least 100 MPa. A single-layer hard coating is bonded to the first and/or second surface of the ultrathin tempered glass foldable substrate without an adhesive layer. The hard coating includes at least one silsesquioxane having a silicon-oxygen core framework directly bonded to the ultrathin tempered glass foldable substrate. The impact resistance defined by a maximum pen drop height without glass failure is at least four times greater than the ultrathin tempered glass foldable substrate without the hard coating. The hard coating has a surface hardness of at least 7H surface hardness and has a hydrophobic surface with a water contact angle of at least 100°. The coating has a transparency of at least 98 percent compared to uncoated substrates.

Abstract: The present invention provides a transparent EMI shielding film that includes a first transparent polymeric substrate layer. A first conductive mesh layer having a first pattern is printed on the first layer, the conductive mesh having a line width from approximately 5 μm to approximately 500 μm and having a space between two adjacent conductive lines of 100 μm to 1000 μm. The conductive mesh blocks electromagnetic signals. A second transparent polymeric layer is positioned over the first transparent polymeric substrate layer having the first conductive mesh layer printed thereon. A second conductive mesh layer having a second pattern is printed on the second transparent polymeric layer, the second pattern being substantially identical to the first pattern, and being substantially identically positioned above the first pattern in order to maximize transparent spaces between adjacent conductive lines. The transparency is approximately 80% or greater in a visible light spectral region.
