▎ 摘　　要

NOVELTY - The present invention provides a method for transferring graphene layer, comprising following steps: (a) providing a support frame; (b) providing the support frame into an etching solution; (c) providing a first substrate with the graphene layers into the support frame to perform etching; (d) replacing the etching solution with a aqueous solution; (e) providing a second substrate into the aqueous solution; and (f) transferring the graphene layer on the second substrate. The method of the present invention is free of any polymer materials as a supporting layer. The method does not merely avoid remaining polymer materials on the graphene layer, but the product still also has excellent material properties.
