中文摘要： MXene是一种新型的类石墨烯2-D纳米材料，有望在微电子、信息、能源、材料和生物医药等领域获得重大应用。本研究首先通过化学刻蚀三元层状MAX相陶瓷材料的方法制得结构可控的MXene二维纳米材料，然后将其表面进行化学修饰或改性，提高其在不同溶剂中的均匀分散/溶解能力，最后开展MXene在润滑油中的摩擦学行为研究。通过本项目的研究，实现类石墨烯MXene纳米材料的可控制备，认识和揭示其超微结构、形成机理和调控机制。探究MXene材料组成、微观结构与磨损表面的形貌特征及磨损的物理、化学过程的内在关系，建立其微结构与摩擦学行为之间的摩擦润滑作用机制，为MXene材料的可控制备及在摩擦学领域中的广泛应用提供基础数据和理论指导。

英文摘要： As a new kind of graphene-like 2-D nanosheet materials, MXene is expected to be applied extensively in the microelectronics, information, energy, materials and biological medicine research fields. In this study, 2-D MXene nanomaterials were synthesised using layered ternary carbides ceramic (MAX phase) materials via a chemical etching methods firstly. In order to improve the miscibility and dispersion stability of MXene in nonpolar solvent, the surface of MXene was modified with a specified surface treating agent via wet route. Finally, The tribological properties of the prepared MXene as an additive in lubricating oil were investigated. It is expected that through the research of project, the controllable preparation of graphene-like MXene nanomaterials will be realized and the microstructure, mechanism of formation and regulation will be understood and revealed. Through the research of the internal relations between material composition, microstructure and wear morphology features, physical and chemical processes, the friction and lubrication mechanism between microstructure and tribological behavior will be established. The results of the project would provide basic data and theoretical guidance for the controllable preparation and tribological application of MXene nanomaterials.
