▎ 摘　　要

NOVELTY - A powdery carbon structure material is irradiated with electron beam and the surface carbon material is separated in order to manufacture a graphene sheet. USE - Manufacture of graphene sheet for use in nano electronic applications, sensors, batteries, super capacitors and hydrogen storage devices. ADVANTAGE - The graphene sheet having high aspect ratio is manufactured quickly, easily and with improved yield without using strong oxidizer and mechanical distribution techniques. DESCRIPTION OF DRAWING(S) - The drawing shows the block diagram of the manufacture of graphene sheet. (Drawing includes non-English language text)
