  We demonstrate the direct dry transfer of large area Chemical Vapor
Deposition graphene to several polymers (low density polyethylene, high density
polyethylene, polystyrene, polylactide acid and
poly(vinylidenefluoride-co-trifluoroethylene) by means of only moderate heat
and pressure, and the later mechanical peeling of the original graphene
substrate. Simulations of the graphene-polymer interactions, rheological tests
and graphene transfer at various experimental conditions show that controlling
the graphene-polymer interface is the key to controlling graphene transfer.
Raman spectroscopy and Optical Microscopy were used to identify and quantify
graphene transferred to the polymer substrates. The results showed that the
amount of graphene transferred to the polymer, from no-graphene to full
graphene transfers, can be achieved by fine tuning the transfer conditions. As
a result of the direct dry transfer technique, the graphene-polymer adhesion
being stronger than graphene to Si/SiO2 wafer.
