摘要

We report a facile and efficient method to transfer the graphene from a metal substrate to a polymer without removal of the metal substrate. Multilayer graphene was synthesized on a Co substrate, and liquid polydimethylsiloxane (PDMS) was prepared using various curing agent ratios. The quantity of graphene transferred to the cured PDMS could be controlled by the mixing ratio of the curing agent. We produced monolayer graphene on a metal substrate and controlled the transfer of graphene layers to PDMS.
