A method for preparing an optically transparent, superomniphobic glass composition is described. In one aspect, the present disclosure provides a method for preparing a glass composition, including heating a borosilicate glass comprising 45-85 wt. % silicon oxide and 10-40 wt. % boron oxide to form a phase-separated glass comprising an interpenetrating network of silicon oxide domains and boron oxide domains. The method includes removing at least a portion of the boron oxide domains from the phase-separated glass and depositing a hydrophobic silane to provide a porous glass having a hydrophobic silane layer disposed on a portion of the surface thereof, a total pore volume of 15-50 vol. %, and an average pore diameter of 20-300 nm. The method includes, within at least a portion of the volume of the porous glass, forming an aerogel precursor, and converting at least a portion of the aerogel precursor to an aerogel.

A super-hydrophobic film layer, a preparation method thereof, and a product thereof are provided, the preparation method includes using a siloxane monomer as a reaction material to form a super-hydrophobic film layer on a surface of a substrate by a plasma enhanced chemical vapor deposition.

A cover article is described herein that includes: a substrate having a primary surface; an optical structure disposed on the primary surface, wherein the optical structure comprises an optical coating and a scratch resistant layer, and wherein the optical coating has an outer surface; and an easy-to-clean (ETC) coating disposed on the outer surface of the optical coating, wherein the ETC coating comprises a fluorine-containing material. The outer surface of the optical coating has a surface roughness (Ra) less than 1.5 nm. The optical structure has a physical thickness of greater than or equal to 500 nm and a maximum hardness of 10 GPa or greater, as measured on the outer surface of the optical coating by a Berkovich Indenter Test along an indentation depth of 50 nm or greater. The scratch resistant layer has a physical thickness from 200 nm to 5000 nm.

An electronic device according to various embodiments of the disclosure may include a housing including a first plate forming an outer face. The first plate may include a glass plate including a first surface outwardly facing the housing and a second surface inwardly facing the housing, a coating layer including an anti-reflection coating and/or an anti-finger coating above the first surface while forming the outer face, a first layer formed between the first surface of the first glass plate and the coating layer, having a first thickness, and including a first inorganic material, a second layer formed between the first layer and the coating layer, having a second thickness, and including a second inorganic material different from the first inorganic material, a third layer formed between the second layer and the coating layer, having a third thickness thicker than each of the first thickness and the second thickness, and including a third inorganic material, and an opaque layer formed on the second surface. Various other embodiments may also be possible.

This disclosure is directed to an improved process for making glass articles having optical coating and easy-to clean coating thereon, an apparatus for the process and a product made using the process. In particular, the disclosure is directed to a process in which the application of the optical coating and the easy-to-clean coating can be sequentially applied using a single apparatus. Using the combination of the coating apparatus and the substrate carrier described herein results in a glass article having both optical and easy-to-clean coating that have improved scratch resistance durability and optical performance, and in addition the resulting articles are “shadow free.”
