High-yield production of graphene-polymer devices requires robust, reliable transfer of chemical-vapor-deposition-grown graphene from the metal growth substrate to polymer films. Transfer success directly depends on the adhesion strength between graphene and the polymer relative to that between graphene and its native metal substrate. We demonstrate control over graphene-polymer adhesion by using solvent-polymer interactions to create favorable electrostatic interactions at the graphene-polymer interface. Using polarization modulated infrared reflection absorption spectroscopy (PM-IRRAS), we observe polymer chain rearrangement at the interface with neat single-layer graphene relative to the arrangement at the interface with copper. These data are measured for pressed unmodified polymer films soaked in different solvents, and we further demonstrate that polymer-solvent interactions can be used to control the polymer rearrangement induced at the graphene interface. Our results indicate the possibility of engineering solvent-polymer interactions to optimize graphene-transfer fidelity via interfacial interactions, and pave the way towards high-yield production of devices using graphene-polymer films.
