Investigation of tribological properties of MXenes

MXenes是一类新的二维材料。与石墨烯、h-BN和MoS 2相比，这些材料在生产高质量2D薄膜方面有更大的选择余地。MXenes在应用于相互滑动的材料表面时也表现出低摩擦和粘附力。然而，已经生产了有限数量的MXene，并且很少研究由MXene润滑的表面的摩擦和磨损。 维也纳科技大学的Gachot小组一直是开发这些用于表面润滑和磨损保护的材料的领导者。这项拟议的国际合作将使卡尔加里大学的Egberts小组能够进行基础原子力显微镜研究，以测量这些材料在原子和分子长度尺度上的摩擦、形貌和机械性能。这些信息将用于支持这些材料在工程规模的摩擦测试实验，在维也纳理工大学进行的操作的机械和物理的理解。这笔资金还将用于支持一名理学硕士学生一年，并为该学生和一名博士后访问维也纳理工大学提供国际经验。此外，作为此次资助机会的一部分收集的数据将用于在加拿大和奥地利开发进一步的合作赠款，包括国际联盟和奥地利科学基金赠款。

MXenes are a new class of two dimensional material. These materials promise a greater choice in production of high quality 2D films, compared with graphene, h-BN, and MoS2. MXenes also exhibit low friction and adhesion when applied onto the surfaces of materials that slide against each other. However, a limited number of MXenes have been produced and very few studies of friction and wear of surfaces lubricated by MXenes. The Gachot group at the Vienna University of Technology has been a leader in developing these materials for lubrication and wear protection of surfaces. This proposed international collaboration will allow the Egberts group at the University of Calgary to conduct fundamental AFM studies to measure the friction, topography, and mechanical properties of these materials at the atomic and molecular length scale. This information will be used to support a greater mechanistic and physical understanding of the operation of these materials in engineering-scale tribotesting experiments, conducted at the Vienna University of Technology. This funding will also be used to support one MSc student for one year and provide an international experience for this student and a postdoctoral fellow to visit the Vienna University of Technology. Further, the data gathered as part of this funding opportunity will be used for the development of further collaborative grants in Canada and Austria, including the Alliance International and Austrian Science Fund grants.
