Nebraska-Rouen Collaborations: Hyperbranched Polar Polymers as Solid Lubricants

该项目将解决材料加工和制造中的一个非常基本的组成部分：将极性聚合物接枝到固体纳米材料的表面，以创建金属有机框架（MOFs）。 该项目将汇集三个具有高度专业知识的研究小组，以跨学科的方法研究表面腐蚀，缺陷修复和MOFs上的聚合物结合，以及研究接枝过程的动力学。 我们的目标是开发固体润滑剂，这是必不可少的制造工艺和应用的材料在高要求的环境，如长期的生物医学植入物。 这一方法从未被尝试过，将对固体润滑剂材料研究领域做出重大贡献。研究新工艺以开发材料的新性能对于创造材料在生物医学设备和汽车制造等各种应用中的用途至关重要。固体润滑剂在汽车制造业中将是非常宝贵的应用，因为汽车制造业对磨损保护有严格的标准。该合作还将向内布拉斯加大学林肯分校的美国学生和博士后介绍鲁昂大学的设施和专业知识，并提供有价值的培训，使美国能够培养具有全球竞争力的科学人才。

This project will address a very fundamental component in materials processing and manufacturing: grafting polar polymers to surfaces of a solid nanomaterial to create metal-organic frameworks (MOFs). This project will bring together three research groups with highly specialized expertise in an interdisciplinary approach to investigate surface corrosion, defect repair, and polymer binding on MOFs, as well as examine the kinetics of the grafting process. The goal is to develop solid lubricants which are essential in manufacturing processes and in applications of materials in highly demanding environments, such as long-term biomedical implants. This approach, which has never been attempted, would be a significant contribution to the field of materials research into solid lubricants.Research into new processes to develop new properties of materials is critical to creating uses for materials in applications as varied as biomedical devices and automotive manufacturing. Solid lubricants would be invaluable applications in automotive manufacture where there are stringent standards for wear protection. The collaboration will also introduce US students and postdocs at the University of Nebraska-Lincoln to the facilities and expertise available at the Universite de Rouen and provide valuable training to enable the US to develop a globally competitive science workforce.
