Investigation of tribological properties of MXenes

MXenes是一类新的二维材料。与石墨烯、h-BN和MoS2相比，这些材料有望在生产高质量2D薄膜方面提供更多的选择。当MXenes应用于相互滑动的材料表面时，也显示出低摩擦力和粘附性。然而，MXenes的生产数量有限，关于MXenes润滑表面的摩擦和磨损的研究很少。维也纳工业大学的加乔特小组在开发这些用于表面润滑和磨损保护的材料方面一直处于领先地位。这项拟议的国际合作将使卡尔加里大学的埃格伯茨小组能够进行基础AFM研究，以在原子和分子长度的尺度上测量这些材料的摩擦、地形和机械性能。这些信息将被用来支持在维也纳理工大学进行的工程规模摩擦试验中更好地从机械和物理上了解这些材料的运行情况。这笔资金还将用于支持一名硕士学生为期一年，并为这名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，作为这一筹资机会的一部分而收集的数据将用于在加拿大和奥地利发展更多的合作赠款，包括国际联盟和奥地利科学基金的赠款。

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.
