▎ 摘　　要

NOVELTY - Eco-friendly graphene sheet (100) comprises a graphene layer (120) directly attached on a base sheet (110) and continuously arranged in a plane. The graphene layer is transferred from an artificial graphite sheet. The base sheet is made of polymer sheet, glass or ceramic substrate. The polymer sheet is provided with a light transparent film. USE - The eco-friendly graphene sheet is useful in sensors, batteries, supercapacitors, hydrogen storage systems and reinforcing fillers in nano-composites for many applications. ADVANTAGE - The sheet can produce graphene oxide through an environmentally friendly process compared to the existing graphene sheet manufacturing process, removes waste oxidizing agents generated in the process of producing graphite oxide and recycles waste acids, but makes these processes work under continuous processes. An eco-friendly and efficient graphene sheet can be manufactured. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the eco-friendly graphene sheet. 100Eco-friendly graphene sheet 110Base sheet 120Graphene layer
