Abstract: Thermoplastic polyurethane has a wide range of industrial applications, but its stiffness and strength limit its performance. Graphene oxide can be introduced as a nanofiller into thermoplastic polyurethane to enhance its properties, but it also has certain drawbacks. In order to improve the above situation, a modified graphene oxide/thermoplastic polyurethane nanocomposite material is proposed. In response to the poor dispersibility of traditional graphene, a study was conducted to modify it with isophorone diisocyanate. Based on this, the modified graphene oxide was introduced into thermoplastic polyurethane through a solution method to prepare the final composite material. The experimental results showed that the carbonyl hydrogen bonding content of the composite material reached 84.79%, and the degree of hydrogen bonding increased significantly; The tensile strength and fracture elongation of composite materials are 35.88 MPa and 569%, respectively. Compared with traditional materials, the tensile strength and fracture elongation have increased by 495% and 92.97%, respectively. Therefore, the modified graphene oxide proposed in the study can effectively improve the microstructure and macroscopic properties of TPU, which is of great significance for its performance enhancement and industrial applications.
