Abstract:
Described herein are various articles that have anti-reflection properties, along with methods for their manufacture and use. The anti-reflection properties are imparted by way of an integral anti-reflection component on a surface of the articles. The articles exhibit a specular reflectance that is less than or equal to about 85 percent of a specular reflectance of the glass substrate alone when measured at wavelengths of about 450 nanometers to about 750 nanometers. The article may also exhibit a specular reflectance of less than 4 percent across the same spectrum.
Abstract:
Described herein are articles and methods of making articles, for example glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier are bonded together using a modification (coating) layer, for example an aromatic polymer coating layer, and associated deposition methods and inert gas treatments that may be applied on the thin sheet, the carrier, or both, to control van der Waals, hydrogen and covalent bonding between the thin sheet and the carrier. The modification layer bonds the thin sheet and carrier together with sufficient bond strength to prevent delamination of the thin sheet and the carrier during high temperature processing while preventing a permanent bond during high temperature processing.
Abstract:
Refractory glass-forming tools, including glass-forming molds incorporating protective metal nitride surface coatings, with optional alumina barrier layers disposed between the mold bodies and coating for high-temperature nitride coating stability, offering particular advantages for the manufacture by direct molding of optically finished glass products such as information display cover glasses from refractory alkali aluminosilicate glasses at molding temperatures up to and above 800° C.
Abstract:
A patterned article and a method of making the patterned article. The patterned article comprises a glass substrate and black matrix segments. The black matrix segments are in the form of a pattern and at least one of the segments has a line width of 8 μm or less. The article also comprises an adhesion agent positioned between the glass substrate and the black matrix segments. The adhesion agent provides at least one of: a total surface energy of 65 mN/m or less and at least a 30% reduction in surface polarity compared to a control untreated glass surface as determined by H2O and diiodomethane contact angle and application of the Wu model.
Abstract:
Methods of forming a glass article are disclosed. In one embodiment, a method of forming a glass article includes translating a pulsed laser beam on a glass substrate sheet to form a laser damage region between a first surface and a second surface of the glass substrate sheet. The method further includes applying an etchant solution to the glass substrate sheet to remove a portion of the glass substrate sheet about the laser damage region. The method may further include strengthening the glass substrate sheet by an ion-exchange strengthening process, and coating the glass substrate sheet with an acid-resistant coating. Also disclosed are methods where the laser damage region has an initial geometry that changes to a desired geometry following the reforming of the glass substrate sheet such that the initial geometry of the laser damage region compensates for the bending of the glass substrate sheet.
