MXenes have emerged as promising materials for various mechanical applications due to their outstanding physicochemical merits, multilayered structures, excellent strength, flexibility, and electrical conductivity. Despite the substantial progress achieved in the rational design of MXenes nanostructures, the tutorial reviews on the mechanical properties of self-standing MXenes were not yet reported to our knowledge. Thus, it is essential to provide timely updates of the mechanical properties of MXenes, due to the explosion of publications in this filed. In pursuit of this aim, this review is dedicated to highlighting the recent advances in the rational design of self-standing MXene with unique mechanical properties for various applications. This includes elastic properties, ideal strengths, bending rigidity, adhesion, and sliding resistance theoretically as well as experimentally supported with various representative paradigms. Meanwhile, the mechanical properties of self-standing MXenes were compared with hybrid MXenes and various 2D materials. Then, the utilization of MXenes as supercapacitors for energy storage is also discussed. This review can provide a roadmap for the scientists to tailor the mechanical properties of MXene-based materials for the new generations of energy and sensor devices.
由于其出色的物理化学特性、多层结构、优异的强度、柔韧性和导电性，MXenes已成为各种机械应用中颇具前景的材料。尽管在MXenes纳米结构的合理设计方面取得了重大进展，但据我们所知，尚未有关于自支撑MXenes力学性能的教程综述报道。因此，鉴于该领域出版物的激增，及时更新MXenes的力学性能至关重要。为实现这一目标，本综述致力于突出在合理设计具有独特力学性能的自支撑MXenes以用于各种应用方面的最新进展。这包括从理论上以及通过各种代表性范例进行实验支持的弹性性能、理想强度、弯曲刚度、附着力和滑动阻力。同时，将自支撑MXenes的力学性能与混合MXenes和各种二维材料进行了比较。此外，还讨论了MXenes作为超级电容器用于能量存储的应用。本综述可为科学家们提供一个路线图，以针对新一代能源和传感器设备定制基于MXene的材料的力学性能。
