The mechanical properties of the polymer matrix are crucial for forming a stable and dense transfer film between the friction pairs, facilitating friction reduction and wear resistance. This work introduces a novel polyurethane composite (PUC) system, prepared by incorporating the MXene (Ti3C2Tx) into a polyurethane elastomer, which exhibits a robust strength of ~ 64 MPa and an excellent toughness of ~ 155.8 MJ/m3. The PUC containing 0.5 wt % MXene (PUC0.5) exhibited excellent tribological properties, with the friction coefficient and wear rate (66 N, 0.54 m/s) reduced by 45.1 % and 206 % in comparison to pure PU, respectively. The excellent tribological properties of PUC0.5 are attributed to exceptional mechanical properties and low shear of MXene.
