We report a transferring method of graphene nanoplatelets (GNPs) on polyurethane (PU) block copolymers film. We polymerized PU block copolymer films, and then, a GNP layer, deposited on glossy paper by drop casting, was transferred by hot press from the glossy surface to the synthetized PU substrate. Nanoindentation test showed that GNP coated PU substrate exhibits improved mechanical properties with respect to the neat PU film. When an electric bias was applied to the GNP coating, the heat generated by Joule effect was transferred to the PU substrate showing an electroactive shape recovery effect.
