CAREER: Outerwall-selectively Functionalized Double-Wall Carbon Nanotubes--Optical and Electrical Properties of Semiconducting Nanotubes in a Multifunctional Carbon Shell

化学系的大分子、超分子和纳米化学（MSN）项目将支持马里兰大学帕克分校王玉煌教授的CAREER研究和教育项目。Wang教授和他的学生将开发新的双壁碳纳米管的功能化化学，它将保留原始的单壁碳纳米管的显着的光学和电子特性。这种外壁概念代表了对当前利用单壁碳纳米管的方法的重大背离，并专注于通过微妙的表面修饰来保护其特性。王教授和他的学生将测量双壁碳纳米管内管的光和电输运特性，并将其与原始单壁碳纳米管、双壁碳纳米管和功能化单壁碳纳米管进行比较。这些努力将为碳纳米材料的化学研究提供新的思路，并为研究人员提供新的化学和纳米计量学工具，以揭示和控制局部化学环境如何调节纳米结构的电子特性。这项研究的成功完成将使双壁碳纳米管在广泛的应用中得到应用，例如作为电子设备和太阳能电池的涂层，以及作为生物医学成像探针和药物输送载体。王教授的职业教育计划包括开发纳米材料的创新课程，并为高中生（包括在纳米科学和纳米技术领域未被充分代表的群体的学生）开展拓展活动。

The Macromolecular, Supramolecular and Nanochemistry (MSN) program of the Division of Chemistry will support the CAREER research and education program of Prof. YuHuang Wang of University of Maryland College Park. Prof. Wang and his students will develop new functionalization chemistry for double-wall carbon nanotubes, which will retain the remarkable optical and electronic properties of pristine single-walled carbon nanotubes. This outerwall concept represents a significant departure from current approaches that utilize single wall carbon nanotubes and focus on protecting their properties through delicate surface modifications. Prof. Wang and his students will measure the optical and electrical transport properties of the inner tube of double wall carbon nanotubes and benchmark them against those of pristine single-walled nanotubes, double-wall nanotubes and functionalized single-walled nanotubes. These efforts will shed new light on carbon nanomaterials chemistry and afford researchers new chemical and nanometrology tools to reveal and control how local chemical environments mediate the electronic properties of nanostructures.Successful completion of the proposed study will enable the use of double-wall carbon nanotubes in a wide range of applications for example as coatings in electronic devices and solar cells and as biomedical imaging probes and drug delivery carriers. The CAREER educational plans of Prof. Wang involve the development of an innovative curriculum in nanomaterials and outreach activities for high school students including students from under-represented groups in the area of nanoscience and nanotechnology.
