Abstract
A method for delaminating a graphene layer from a metal catalyst substrate. The method includes depositing the graphene layer on the metal catalyst substrate to form a layered structure and soaking the layered structure in a water-based solution comprising water and a water-miscible organic solvent such that the water-based solution intercalates between the graphene layer and the metal catalyst substrate and oxidizes the metal catalyst substrate for delamination of the graphene layer from the metal catalyst substrate.
