▎ 摘　　要

NOVELTY - A multilayer graphene tape is continuously produced over 500 m long and a planned width of 20-200 cm by obtaining free carbon atoms from graphite rod heated by photons from numerous diode lasers in a cuboid chamber through which helium gas flows at a speed of 50-200 m/s, where helium transfers kinetic energy at the planned speed to deposit free carbon atoms to moving substrate belt with a graphene spore to form multilayer graphene tape. USE - Production of multilayer graphene tape in a continuous manner. ADVANTAGE - The resulting multi-layer tape is of high purity and repeatable quality.
