摘要
二维层状材料不仅具有极高的承载能力,并且凭借其超薄的厚度在摩擦过程能较容易地进入摩擦接触区.因此,它们在减少摩擦和磨损方面具有巨大的研究和应用潜力.Mxenes作为一种类似于石墨烯的二维层状材料,具有独特的结构和丰富的官能团,其中Ti3C2Tx Mxenes因低层间剪切阻力、高比表面积、良好的分散性等优点而被广泛用作润滑添加剂.本文主要介绍了二维层状Ti3C2Tx的主要制备方法,包括"自上而下"和"自下而上"两种制备路线.同时对二维Ti3C2Tx作为液体润滑剂添加剂、固体润滑涂层添加剂、复合材料增强相的摩擦学应用及效果进行综述,并对其润滑机制进行了探讨.进一步对二维Ti3C2Tx的制备技术的发展和其作为新型润滑材料的应用前景作出展望.
Abstract
The two-dimensional layered material not only has a very high load bearing capacity,but also can easily enter the friction contact zone during the friction process by virtue of its ultra-thin thickness.Therefore,they have great research and application potential in reducing friction and wear.As a two-dimensional layered material similar to graphene,Mxenes has a unique structure and rich functional groups.Among them,Ti3C2Tx Mxenes is widely used as a lubricating additive because of its advantages such as shear resistance between low layers,high specific surface area and good dispersion.This paper mainly introduces the main preparation methods of two-dimensional layered Ti3C2Tx,including"top-down"and"bottom-up"preparation routes.The tribological applica-tions and effects of 2D Ti3C2Tx as liquid lubricant additive,solid lubricant coating additive and composite reinforce-ment phase are reviewed,and the lubrication mechanism of Ti3C2Tx is discussed.Further,the development of 2D Ti3C2Tx preparation technology and its application as a new lubrication material are prospected.
