POLY(ETHYLENE CO-VINYL ACETATE)-ASSISTED ONE-STEP TRANSFER OF ULTRA-LARGE GRAPHENE

One-step roll-to-roll lamination transfer of graphene was achieved by poly(ethylene co-vinyl acetate) as a binding material which has thermoplastic property and wide rubbery-plateau region between T-g similar to T-m. The transferred graphene film has a transmittance of 96.7% at 550nm and 1.96 k Omega/sq of sheet resistance measured by simple 4-probe method. Standard deviation was found to be 0.198 k Omega/sq.
