Investigation of tribological properties of MXenes

点击翻译按钮获取中文摘要

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.
