Poor lubrication and wear performance in moving mechanical and biological systems impact all of humanity. Specific to mechanical systems, approximately 860 million tonnes of CO2 emissions per year can be eliminated through improvements in lubrication technologies. This project directly addresses this issue by examining novel dry lubricants comprised of layered 2D materials, termed "van der Waals heterostructures" (vdHW) as a mechanism to exquisitely control the friction and wear properties of surfaces. The proposed project will be focussed on measuring the mechanical stiffness, surface adhesion reduction, and lubrication performance of the vdHW. The impact of surface contamination and water/liquid intercalation on these materials will also be examined through controlled humidity experiments. This project will result in the training of one postdoctoral fellow, two MSc students, and two undergraduate research students, as well as provide support for the collaborative work on the development of nanoadditive lubricants. Given the early stage of development of these materials in industry, the work will provide the foundation for the future application of vdWH as additives in nanoenhanced lubricants. Concurrent development of vdWH with other projects in the applicant's group examining nanoenhanced lubricants, supported by Calgary L&G, will facilitate the knowledge transfer from the lab to industry for these materials. This fundamental approach and innovation pathway will be a key component in ensuring Alberta and Canada's competitiveness in the lubricant synthesis sector. Finally, the training opportunities offered to HQP will ensure that Alberta and Canada have sufficient trained experts to support continued excellence in lubrication science and technology.

在移动机械和生物系统中，润滑不良和磨损性能会影响所有人类。针对机械系统，每年约有8.6亿吨二氧化碳排放可以通过改进润滑技术来消除。该项目通过研究由分层的2D材料组成的新型干润滑剂直接解决此问题，称为“范德华异质结构”（VDHW），作为一种机制，可以精确控制表面的摩擦和磨损特性。提出的项目将集中在测量VDHW的机械刚度，表面粘附降低和润滑性能上。表面污染和水/液体插入对这些材料的影响也将通过受控的湿度实验进行检查。该项目将导致一名博士后研究员，两名MSC学生和两名本科研究专业的培训，并为纳米降低润滑剂开发的协作工作提供支持。鉴于这些材料在工业中开发的早期阶段，这项工作将为将来将VDWH作为纳米碳润滑剂中的添加剂提供基础。在Calgary L＆G支持的申请人小组中，VDWH以及申请人小组中的其他项目的同时开发将有助于这些材料从实验室到行业的知识转移。这种基本方法和创新途径将是确保艾伯塔省和加拿大在润滑剂合成部门的竞争力的关键组成部分。最后，向HQP提供的培训机会将确保艾伯塔省和加拿大拥有足够的培训专家，以支持持续的润滑科学和技术卓越表现。
