▎ 摘  要

This paper addresses a low damage-transfer method using epoxy bonding. In this method, first, graphene/metal film and a target substrate are bonded using epoxy; etching of the metal substrate follows. This method is free of organic particles caused by PMMA, and no cracks are spotted, which cracks are a major concern in the PMMA-transfer method. Raman data show that the epoxy-transferred graphene films have a higher 2D/G intensity ratio and a narrower 2D FWHM than those of films transferred by PMMA, if the epoxy is cured optimally. The Raman spectrum of the epoxy-transferred graphene showed G band splitting, probably due to the strain effect. This method is useful for the transfer of large area-graphene films.
