Abstract

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 (Ti₃C₂T_x) 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 (PUC_0.5) 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 PUC_0.5 are attributed to exceptional mechanical properties and low shear of MXene.

研究 MXene 增强聚氨酯复合材料在干燥条件下的摩擦学特性

聚合物基体的机械性能对于在摩擦对之间形成稳定致密的转移膜、减少摩擦和提高耐磨性至关重要。本研究介绍了一种新型聚氨酯复合材料（PUC）系统，该系统是通过在聚氨酯弹性体中加入 MXene（Ti3C2Tx）制备而成，具有 64 兆帕（MPa）的高强度和 155.8 兆焦耳/立方米（MJ/m3）的卓越韧性。含有 0.5 wt% MXene 的 PUC（PUC0.5）具有优异的摩擦学特性，与纯聚氨酯相比，摩擦系数和磨损率（66 N，0.54 m/s）分别降低了 45.1 % 和 206 %。PUC0.5 的优异摩擦学特性归功于 MXene 的优异机械特性和低剪切力。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
