Abstract
A method for dry graphene transfer comprising growing graphene on a growth substrate, chemically modifying a transfer substrate to enhance its adhesion to graphene, contacting the graphene on the growth substrate with the transfer substrate and transfer printing; and separating the transfer substrate with attached graphene from the growth substrate. The growth substrate may be copper foil. The transfer substrate may be a polymer, such as polystyrene or polyethylene, or an inorganic substrate. Also disclosed is the related composite material made by this process.
