▎ 摘　　要

NOVELTY - Production of graphene foil with pre-defined number of graphene layers involves successively performing step (a) of producing graphene on metallic substrate, step (b) of depositing polymer layer on graphene surface, step (c) of separating polymer/graphene stack from metallic substrate, step (d) of transferring obtained polymer/graphene stack directly onto metallic substrate with greater than or equal to 1 graphene layer deposited on top, and step (e) of separating polymer/graphene/graphene stack from metallic substrate. USE - Production of graphene foil with pre-defined number of graphene layers. ADVANTAGE - The method enables rapid production of high quality graphene foil with pre-defined number of graphene layers. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram of the preparation method of graphene foil with pre-defined number of graphene layers.
