    Abstract: 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 multilayered modification (coating) layer, for example an alternating cationic/anionic polymer coating layer, and associated deposition methods, 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 (≤400° C.) processing while also preventing formation of a permanent bond between the sheets during such processing.

    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 a cationic polymer coating layer, and associated deposition methods, 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 (≤600° C.) processing while also preventing formation of a permanent bond between the sheets during such processing.

    Abstract: Methods of forming a foldable apparatus can involve contacting an existing first major surface of a foldable substrate with an alkaline solution to remove an outer layer to form a new first major surface. In aspects, the alkaline solution comprises about 10 weight % or more of a hydroxide-containing base and/or a pH of about 14 or more. Methods of forming a foldable apparatus can comprise contacting a first major surface of a foldable substrate with a first alkaline detergent solution under sonication. Methods of forming a foldable apparatus can comprise contacting an existing first major surface of a foldable substrate with an acidic solution having a pH from about 3.3 to about 3.5 and a fluorine-containing compound. Methods of forming a foldable apparatus can comprise contacting an existing first major surface of a foldable substrate with a solution comprising fluorosilicic acid.
