Abstract(#br)Graphene has been attracting great attention from scientific community due to its astonishing mechanical, optical, and electrical properties, especially, graphene films synthesized by chemical vapor deposition (CVD) method are large, uniform and high-quality. CVD-grown graphene films have been successfully transferred onto various kinds of substrates such as SiO 2 /Si, quartz, PET, and plastics. However, graphene transfer onto polydimethylsiloxane (PDMS) substrates for device development has been limited due to the very low surface energy of PDMS.

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.
