Lubricant-infused surfaces are increasingly used in many technologies from water collection in arid areas, hydrodynamic drag reduction over ship hulls, to antifouling and self-cleaning surfaces of sensors for automated detection in advanced manufacturing. Interfacial nanobubbles have been found to significantly enhance performance of lubricant-infused surfaces in hydrodynamic drag reduction, due to nanobubble-mediated interfacial transport. However, the current research challenge is on-demand generation of nanobubbles on lubricant-infused surfaces. By leveraging the best international expertise, the objective of this collaboration is to overcome the current challenge by establishing an innovative platform for nanobubble formation on slippery surfaces. As a pioneer on interfacial slip, the international collaborators from University of Sydney, Australia, will bring their world-class expertise to the project. This project will allow for Canadian researchers initiating the international project of a cutting-edge research topic of global importance. The collaboration will strengthen the leadership of Canada in the areas of soft matter, advanced manufacturing and technology development for Internet-of-Things. In addition to platform technology for superior performance of antifouling surfaces, the expected outcomes from the project will be development of productive and lasting international collaboration, outstanding HQP training opportunities, and joint publications in impactful journals.

注入润滑油的表面越来越多地应用于许多技术，从干旱地区的水收集，船体的水动力阻力减少，到先进制造中自动检测传感器的防污和自清洁表面。由于纳米气泡介导的界面传输，界面纳米气泡显著提高了润滑油注入表面在水动力减阻方面的性能。然而，目前的研究挑战是在注入润滑剂的表面上按需生成纳米气泡。通过利用国际上最好的专业知识，这次合作的目标是通过建立一个创新的平台来克服当前的挑战，在光滑的表面上形成纳米气泡。作为界面滑移的先驱，来自澳大利亚悉尼大学的国际合作者将为该项目带来世界一流的专业知识。该项目将允许加拿大研究人员发起具有全球重要性的前沿研究课题的国际项目。此次合作将加强加拿大在软物质、先进制造和物联网技术开发领域的领导地位。除了具有卓越防污表面性能的平台技术外，该项目的预期成果将是发展富有成效和持久的国际合作，提供出色的HQP培训机会，并在有影响力的期刊上联合发表文章。
