The research objective of this award is to study, a new class of nanocomposite materials termed covetics, and compare their behavior to their respective base materials. The nanocomposites consist of a metal matrix and carbon nanofillers which are combined with metal in a new way. The carbon-metal bond is strong and the carbon does not separate out during remelting, laser ablasion or magnetron sputtering. Preliminary results have shown that these materials exhibit some unique structural features and deformation behaviors not seen in traditional metals, and have superior properties to the base metals. However, fundamental knowledge of these materials is lacking. The proposed university-industry collaborative project between the University of Illinois at Urbana-Champaign and Third Millennium Metals, LLC will address the multi-scale experimental study of the structure and composition, and mechanical, thermal and electrical properties of these materials. These will serve as inputs and validation for multi-scale modeling of these newly discovered materials.If successful, these studies would lead to a fundamental understanding of these new materials, would stimulate further research on covetics, and facilitate a transition from scientific discovery to commercialization and applications including energy, thermal management, transportation, and environment. The proposed research may potentially lead to new discoveries regarding material structure, bonding, and/or new deformation mechanisms. The knowledge gained would lead to more accurate predictions of properties of nanocomposites, new materials? designs, and more reliable structures, in general. The educational plan focuses on course development and incorporation of findings of this research into existing courses on materials. The results will be published and course notes will be posted on the NSF NanoHub website.

该奖项的研究目标是研究一类新的纳米复合材料，称为covetics，并将其行为与各自的基础材料进行比较。纳米复合材料由金属基体和以新方式与金属结合的碳纳米填料组成。碳-金属键很强，在重熔、激光烧蚀或磁控溅射过程中碳不会分离。初步研究结果表明，这些材料具有传统金属所没有的独特结构特征和变形行为，并具有比基体金属更优越的上级性能。然而，缺乏对这些材料的基本知识。伊利诺伊大学厄巴纳-香槟分校和Third Millennium Metals，LLC之间拟议的大学-工业合作项目将解决这些材料的结构和成分以及机械，热和电气性能的多尺度实验研究。这些研究将作为这些新发现材料的多尺度建模的输入和验证。如果成功，这些研究将导致对这些新材料的基本理解，将刺激对covetics的进一步研究，并促进从科学发现到商业化和应用的过渡，包括能源，热管理，运输和环境。拟议的研究可能会导致有关材料结构，粘合和/或新的变形机制的新发现。所获得的知识将导致更准确的预测性能的纳米复合材料，新材料？设计和更可靠的结构。教育计划的重点是课程开发和将这项研究的结果纳入现有的教材课程。结果将被公布，课程笔记将在NSF NanoHub网站上发布。
