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 DEG C) processing while also preventing formation ofa permanent bond between the sheets during such processing. 本文描述了制品及制造制品(例如玻璃制品)的方法，所述制品包含薄片材和载体，其中，所述薄片材和载体利用改性(涂)层，例如包含阳离子表面活性剂的涂层或包含有机盐的涂层结合在一起，以及相关的沉积方法。改性层利用足够的结合强度将薄片材和载体结合在一起，以防止薄片材和载体在高温(？500℃)加工期间分层，同时还防止在所述加工期间在片材之间形成永久结合。
