Proposal Number: CTS-0646015Principal Investigator: Fisher, Timothy S.Affiliation: Purdue UniversityProposal Title: SGER: Interfacial Thermal Transport Across Carbon Nanotube Arrays Today, new materials can be designed at the atomic level and are projected to improve the efficiency of information processing, heat transfer, and energy conversion. Improved understanding and optimization of therma energy transport through solid-solid interfaces could enabel a wide range of advances in applications relevant to almost every technological enterprise. The proposed exploratory research seeks to address these challenges with an innovative solution that exploits the many unique characteristics of carbon nanotubes (CNTs). The intellectual merit of the proposed work derives from the development of detailed understanding ofinterfacial heat transfer from bulk materials through carvon nanotube arrays, with the untimate aim of improving therma interface conductance. Thermal transport through dense CNT arrays is very complicated, given the billions of heat flow paths that exist and the wide variety of local contact features among individual CNTs and between individual CNTs and buld substrates. Successful demonstration of an accurate technique the extract compontent resistance from such a physically complex structure will produce important new knowledge of thermal transport. In furtherance of broad impacts, results of the proposed work will be incorporated into topics on carbon nanotube properties and applications in two recently developed graduate courses and ner coverage will include thermal and electrical transport and thermo-mechanical properties of carbon nanostructures, as well as a lab module that builds on a provious education NSF grant. The project will also support the educational development of one graduate student from an underrepresented group, and this effort will help to continue the strong and demostrated commitment of the PI in enhancing diversity through the training of graduate and undergraduate students from underrepresented groups.

提案编号：CTS-0646015主要研究者： Fisher，Timothy S. 普渡大学提案标题：SGER：碳纳米管阵列的界面热传输如今，新材料可以在原子水平上设计，并预计将提高信息处理，传热和能量转换的效率。 通过固-固界面对热能传输的更好理解和优化可以在几乎所有技术企业的应用中实现广泛的进步。 拟议的探索性研究旨在通过利用碳纳米管（CNT）的许多独特特性的创新解决方案来应对这些挑战。 所提出的工作的智力价值来自于对通过carvon纳米管阵列从块体材料的界面传热的详细理解的发展，其最终目的是改善热界面电导。 通过密集的CNT阵列的热传输是非常复杂的，因为存在数十亿的热流路径，以及各个CNT之间以及各个CNT和buld衬底之间的各种各样的局部接触特征。 从这样一个物理复杂结构中提取元件电阻的精确技术的成功演示将产生重要的热传输新知识。 为了促进广泛的影响，拟议工作的结果将被纳入两个最近开发的研究生课程中的碳纳米管特性和应用主题中，而新的覆盖范围将包括碳纳米结构的热和电传输和热机械特性，以及建立在NSF资助基础上的实验室模块。 该项目还将支持一名来自代表性不足群体的研究生的教育发展，这一努力将有助于继续PI在通过培训来自代表性不足群体的研究生和本科生来增强多样性方面的强有力和经证实的承诺。
