▎ 摘　　要

NOVELTY - Preparing a graphene structure, comprises doping a first graphene layer and a second graphene layer to a metal chloride and then laminating on a substrate. USE - The method is useful for preparing a graphene structure, which is useful in a transparent electrode and LED (all claimed). ADVANTAGE - The method is capable of simply preparing the graphene structure with high thermal stability and luminous efficiency, and good thermal, electrical, and mechanical properties. The graphene structure improves the electrical property and flexibility of the transparent electrode.
