提案编号：CTS-0646015主要研究员：费希尔，蒂莫西·S隶属关系：普渡大学提案标题：SGER：跨碳纳米管阵列的界面热传输今天，新材料可以在原子水平上设计，预计将提高信息处理、热传输和能量转换的效率。增进对固体-固体界面热能传输的了解和优化，可以在与几乎每个技术企业相关的应用方面取得广泛的进展。拟议的探索性研究试图通过一种创新的解决方案来应对这些挑战，该方案利用了碳纳米管(CNT)的许多独特特性。这项拟议工作的学术价值来自于对块体材料通过Carvon纳米管阵列进行的界面热传递的详细了解，其最终目的是改善界面热导。考虑到存在的数十亿条热流路径以及单个碳纳米管之间以及单个碳纳米管与块状衬底之间的各种局部接触特征，通过致密的碳纳米管阵列的热传输非常复杂。从如此复杂的物理结构中提取组分电阻的精确技术的成功演示将产生重要的关于热传输的新知识。为了促进广泛的影响，拟议的工作成果将纳入最近开发的两门研究生课程中关于碳纳米管性能和应用的主题，NER覆盖的内容将包括碳纳米结构的热和电传输以及热机械性能，以及以国家科学基金会提供的教育拨款为基础的一个实验室模块。该项目还将支持来自任职人数不足群体的一名研究生的教育发展，这一努力将有助于继续国际和平组织坚定和示范的承诺，通过培训来自任职人数不足群体的研究生和本科生来加强多样性。

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.
