▎ 摘　　要

NOVELTY - Preparing graphene super-material involves forming a graphene oxide film on a porous substrate, separating the graphene oxide membrane from the porous substrate, and transferring the graphene dioxide membrane to the surface of a flexible metal substrate to obtain the graphene super material. USE - Method for preparing graphene super material used in thermochromic field for storage, transportation, and daily life. ADVANTAGE - The method allows dynamic optical reflectance modulation to effectively manipulate the color of the graphene metamaterial (CGM), provides large-scale producibility and flexibility of CGM to any curved surface, suggests a broad application prospect in different areas related to dynamic color modulation and environmental monitoring, and provides a graphene metamaterial and application in the field of thermochromism.
