Two-dimensional (2D) nanomaterials such as graphene, MoS_2, and WS₂ have found great applications in recent years. MXenes are the novel 2D nanomaterials that are synthesized generally by selective etching and exfoliation of the MAX phases. M is an early transition metal, A is an element from the A-group and X is the carbon or nitrogen, in MAX phases. Due to the weaker M-A bonds compared with the M-X bonds in MAX phases, the selective etching of the A elements leads to the formation of the 2D MXene nanomaterials. MXene nanosheets have attracted great applications in many fields. Due to their unique mechanical, tribological, thermal, and electrical properties, MXenes can be introduced as the proper reinforcements for the polymeric composites. However, few researchers have focused on the properties of the MXene/polymer nanocomposites. In this review study, it is tried to collect the performed works on the mechanical, tribological, thermal, corrosion, and electrical performances of the thermosetting and thermoplastic polymeric composites reinforced with MXenes.

二维（2D）纳米材料，例如石墨烯，MoS ₂和WS ₂近年来发现了巨大的应用。MXenes是新颖的2D纳米材料，通常通过选择性蚀刻和剥落MAX相来合成。M为早期过渡金属，A为A相中的A组元素，X为MAX相中的碳或氮。由于在MAX相中与MX键相比，MA键较弱，对A元素的选择性刻蚀导致2D MXene纳米材料的形成。MXene纳米片已经在许多领域吸引了广泛的应用。由于其独特的机械，摩擦学，热学和电学特性，MXenes可以作为聚合物复合材料的合适增强材料。但是，很少有研究者关注MXene /聚合物纳米复合材料的性能。在这项审查研究中，尝试收集机械上已完成的工作，
