▎ 摘　　要

NOVELTY - Method for forming a graphene scroll involves inserting a catalyst substrate into a chemical vapor deposition chamber, annealing the catalyst substrate in hydrogen gas within the chemical vapor deposition chamber, exposing the annealed catalyst substrate to reaction gas mixture including a hydrocarbon, synthesizing graphene from the reaction gas mixture, detaching the annealed catalyst substrate from the synthesized graphene, and consolidating the synthesized graphene into a cylindrical multi-wall scroll having a spiral cross-section. USE - Method for forming graphene scroll used for synthesizing graphene article (claimed) e.g. graphene reinforced sheet and graphene reinforced scroll. ADVANTAGE - The method enables formation of graphene scroll with excellent dimensional stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) synthesis of graphene article, which involves passing a metal substrate through a heated chemical vapor deposition chamber at atmospheric pressure, introducing hydrocarbon as a carbon source to form monolayer of large area graphene including crystal hexagonal grains on the metal substrate, forming a thermoplastic film on a surface of the graphene opposite the metal substrate, and detaching the metal substrate from the graphene; and (2) graphene-reinforced article, which comprises a sheet material having major surface (a) opposite to a major surface (b), and a graphene layer joined to major surface(s) of the sheet material, which are rolled to form a multi-walled cylindrical scroll having a yield tensile strength of more than 1 GPa. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of a pure graphene sheet or graphene-polymer sheet rolled into a multi-wall scroll.
