▎ 摘  要

NOVELTY - A graphitized catalyst (110) is formed in 3-dimensional form, a polymeric coating is formed on the graphitized catalyst, and heat-treated in an inert or reduced atmosphere, to obtain graphene shell (100). The thickness of the graphene shell is controlled by adjusting polymeric coating amount, on the graphitized catalyst. USE - Graphene shell used for forming graphene core-shell assembly (claimed) used as hydrogen storage medium and optical fiber. ADVANTAGE - The graphene shell is economical and environmentally-friendly, has excellent flexibility and high mobility, and provides optical fibers with high light transmission speed, reduced light transmission loss. The graphene shell has regular structure and large surface area, and enables safe storage of large quantity of hydrogen and does not degrade by repeated storing and discharging of hydrogen due to the dense molecular structure of hydrogen. The graphene shell having controlled thickness is manufactured. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene core-shell assembly, which consists of 3-dimensional component comprising graphitized catalyst and core. The graphene shell is formed on the surface of 3-dimensional component. DESCRIPTION OF DRAWING(S) - The drawing shows the flowchart of manufacture of graphene shell.
