项目摘要

The objective of this grant is to elucidate the fundamental mechanisms that are responsible for the suppression of wear in graphene-polymer composites. Our goal in this project is to develop an in-depth understanding of the enhanced ability of graphene additives to resist wear in polymers. Graphene is interesting from the point of view of wear suppression since it has in-plane sheet dimensions of the order of several microns coupled with nanometer scale sheet thickness. The microscale dimensions of the graphene sheets enables it to effectively interfere with debris generation processes in polymers, while the nanometer scale thickness, low density and planer sheet geometry of graphene enables a huge interfacial contact area with very large number density of graphene platelets in the matrix. Moreover, the sliding of individual graphene planes within graphene platelets is expected to enhance the lubrication effect and reduce the friction levels in addition to the material wear rates.If successful, the proposed work will provide the fundamental understanding necessary to enable the rational design of wear-resistant graphene polymer composites. The excellent wear suppression ability of graphene fillers coupled with their potentially low production cost makes this technology very promising for industrial applications. Such composites offering reduced friction and wear have a wide range of applications in the aerospace, medical, chemical, automotive and electronics industries. Outreach activities include demonstrations to students from New York State's New Visions high school program. This will help to popularize science and to attract underrepresented groups to careers in science and engineering.
这项资助的目的是阐明石墨烯-聚合物复合材料中抑制磨损的基本机制。我们在这个项目中的目标是深入了解石墨烯添加剂在聚合物中抗磨损的增强能力。从磨损抑制的角度来看,石墨烯是令人感兴趣的,因为它具有几微米量级的平面内片尺寸以及纳米级片厚度。石墨烯片的微米级尺寸使其能够有效地干扰聚合物中的碎片生成过程,而石墨烯的纳米级厚度、低密度和平面片几何形状使得能够在基质中具有非常大的石墨烯片晶数密度的巨大界面接触面积。此外,石墨烯片晶内单个石墨烯平面的滑动有望增强润滑效果,降低摩擦水平以及材料磨损率。如果成功,拟议的工作将为合理设计耐磨石墨烯聚合物复合材料提供必要的基本理解。石墨烯填料优异的磨损抑制能力加上其潜在的低生产成本使得该技术非常有希望用于工业应用。这种提供减少摩擦和磨损的复合材料在航空航天、医疗、化学、汽车和电子工业中具有广泛的应用。外联活动包括向来自纽约州新视野高中项目的学生进行示威。这将有助于普及科学,吸引代表性不足的群体从事科学和工程职业。
