▎ 摘  要

NOVELTY - The formation process involves forming a clean ultrathin flexible glass substrate that has a thickness of 10-300 micrometers. A chemical vapor deposition-grown graphene is contacted on a formation substrate with a thermal release tape to form a stack and is pressed. The formation substrate is etched away in an etchant solution. The glass substrate is contacted with the graphene to form a sandwich structure and is pressed. The sandwich structure is heated to 1-100 degrees C above the release temperature of the tape to remove the tape or the graphene from the flexible glass substrate. USE - Formation process of graphene-coated glass for use in manufacturing of electronic devices. ADVANTAGE - The formation process uses glass substrate that provides dimensional and thermal stability, sample purity, transparency, and surface quality compared to polymer substrates. The combination of a graphene layer on the flexible glass substrate allows for the design and development of a comprehensive technological platform for the fabrication of flexible electronic devices. The combination of the glass substrate with the graphene structure develops new material combinations that impart additional scratch and damage resistance to the glass substrate. DESCRIPTION OF DRAWING(S) - The drawing shows the block diagram of the thermal release tape transfer process in which chemical vapor deposition-grown monolayer of graphene is transferred onto a thin, flexible glass substrate.
