Publication number: 20230103045Abstract: Apparatus and method for treating a substrate, for example texturing a substrate. In some embodiments, a masking material is applied to a surface of the substrate in a predetermined pattern, the surface thereafter contacted with an etchant that removes the masking material. Contacting the surface with the etchant produces multiple co-located textures. In other embodiments, the masking step can be eliminated, and the etchant is applied in a predetermined pattern to produce multiple co-located textures. In still other embodiments, the substrate has a chemical composition, and the substrate is exposed to a leachant that leaches at least one constituent of the chemical composition to produce a substrate with a varying chemical composition at the substrate surface.Type: ApplicationFiled: January 5, 2021Publication date: March 30, 2023Inventors: Gabriel Pierce Agnello, Joy Banerjee, Aize Li, Robert George Manley, Huan-Hung Sheng, Siva Venkatachalam

Publication number: 20210039986Abstract: Methods of processing or modifying a glass substrate such as a glass sheet are disclosed. A method includes contacting at least one of opposing major surfaces of the glass sheet with a fluid applicator apparatus and a liquid etchant composition including acetic acid, ammonium fluoride, and water, the contacting conducted at a predetermined transfer rate of the liquid etchant to the at least one of the opposing major surfaces. The predetermined liquid transfer rate is controlled to adjustably texture the at least one of the opposing major surfaces and provide a textured major surface, wherein when the textured major surface and a planar surface are placed in contact, there is an adhesion force between the textured major surface and the planar surface, and wherein the adhesion force is within a target adhesion force range.Type: ApplicationFiled: March 7, 2019Publication date: February 11, 2021Inventors: Gabriel Pierce Agnello, Tatyana Vyacheslavovna Brown, He Jing, Nikolay Zhelev Zhelev
