In this study, the reinforcement effects of graphene on the properties of bio‐based polyurethane (PU) were studied with the use of 1 wt% three functionalized graphene (dispersible graphene, reduced graphene oxide‐NH 2 , and reduced graphene oxide‐tetraethylene pentamine). Scanning electron microscope (SEM) revealed the relatively homogeneous dispersion of graphene nanoplatelets in the PU matrix. It was found that the addition of 1 wt% of the different graphenes could lead to a significant reinforcement effect on the bio‐based PU. Especially, PU nanocomposite with 1 wt% dispersible graphene exhibited 6°C improvement in the T g , 75% increment in storage modulus at 25°C, 34% increase in tensile strength, and 30% increase in Young's modulus. Practical applications: Different graphene were used to reinforce the bio‐based PU. A significant reinforcement effect of graphene on bio‐based PU was found. This strategy has the potential for the fabrication of advanced bio‐based materials. A significant graphene reinforcement effect on bio‐based PU was found.
