▎ 摘　　要

NOVELTY - An apparatus for manufacturing graphene sheets, comprises: a gas tube (11); a hydrocarbon gas source (13) connected to a front part of the gas tube for providing a hydrocarbon gas through the gas tube; a microwave generator (15) for generating a microwave passing a middle part of the gas tube through a waveguide tube (16) to form a microwave plasma torch (20) from the hydrocarbon gas, where the hydrocarbon gas is cracked by the microwave plasma torch to form graphene sheets; and a tube collector (19) connected to a back part of the gas tube for collecting the graphene sheets. USE - As an apparatus for manufacturing graphene sheets (claimed) useful as heat dissipation glue, heat conduction glue and extremely reinforced composite material. ADVANTAGE - The apparatus manufactures graphene sheets in mass production. A large amount of single-layer graphene sheets (yield greater than or equal to 30%) can be obtained by the apparatus with proper operation parameters. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacturing graphene sheets, involving: providing hydrocarbon gas through a gas tube; providing microwave through waveguide tube to pass middle part of the gas tube and form microwave plasma torch from the hydrocarbon gas, where the hydrocarbon gas is cracked by the microwave plasma torch to form graphene sheets; and collecting the graphene sheets by a tube collector connected to back part of the gas tube. The apparatus further comprises at least one rod collector in the tube collector. The hydrocarbon gas source mixes an inert gas with the hydrocarbon gas to tune a concentration of the hydrocarbon gas. DESCRIPTION OF DRAWING(S) - The figure shows a view of the apparatus for manufacturing graphene sheets.
