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 coating layer comprising a cationic surfactant or a coating layer comprising an organic salt, and associated deposition methods. 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 (? 500° C.) processing while also preventing formation of a permanent bond between the sheets during such processing.
