Polyurethane is a versatile engineering material, which is usually synthesized by polyaddition of polyol, isocyanate, and chain extender. Graphene is a monolayer of carbon atoms packed into honeycomb structure with fascinating thermal, electrical, and mechanical properties. Among the rapidly expanding families of nanocomposite, polyurethane/graphene materials have attracted considerable attention in academia and industry. This article reviews essential aspects of graphenereinforced polyurethane nanocomposite. Various strategies for fabricating polyurethane/graphene nanocomposite have been conversed. Recent developments in the field of polyurethane/graphene nanocomposite (as shape memory, adsorbent, electromagnetic interference shielding, and gas barrier materials), associated challenges, and future potential have been reviewed.
