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 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. (C) 2014 Elsevier Ltd. All rights reserved. (AU)
