US Patent 11999135 Temporary bonding using polycationic polymers

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.
