ABSTRACTProposal Number: CTS-0609157 Principal Investigator: Gilchrist, James F.Affiliation: Lehigh University Proposal Title: NER: Nanoparticle Assembly of Nanowire Composites and Nano- and Microfluidic Vasculature Intellectual MeritThe proposed exploratory research program will develop a method of creating precision self-assembled nano- and micro-structured materials using nanoparticle dielectrophoresis. Two classes of materials result from this process: 1) composites having anisotropic electrical conductivity and thermal transport properties and 2) structures with embedded microvasculature. The feasibility of this process to form embedded nanowire composites will be established and parametric studies will be performed to evaluate the effect of electric field strength and geometry, nanoparticle size and polarization, complex fluid permittivity and elasticity, and matrix solidification on rate of formation and final nanowire structures. Using thermoreversible gels, such nanocomposites may be formed for temporary use and then dissolved and redispersed for re-use. Using dissolution of nanowires grown linearly or fractally along local electric field lines as a template for vasculature, it should be possible to dictate the structure and connectivity of microfluidic networks.Broader Impacts: The ability to directly form nanowire composites in adhesives has the potential to streamline and simplify the processing of various electronic devices. Self assembly of connections between components and substrates without the need for precision alignment may have significant impact on sensor and display production technologies. Creation of microvasculature using the proposed nanoparticle self assembly method could allow point-of-use fabrication of microchemical processes in situations of limited resources such as on the battlefield or in space. This program will directly educate a graduate student and the results generated will be disseminated in courses, in journal publications, at conferences, and any images of an aesthetically pleasing quality will be integrated into a Lehigh Valley Art/Nano project currently under development. The results of the proposed research will significantly impact both the hierarchical nanomanufacturing and nanoscale devices and system architecture areas of the Active Nanostructures and Nanosystems Program.

摘要Propopopal编号：CTS-0609157主要研究者：Gilchrist，James Filiation。纳米颗粒介电性。这一过程产生的两类材料：1）具有各向异性电导率和热传输特性的复合材料以及2）具有嵌入式微脉管系统的结构。将建立此过程形成嵌入式纳米线复合材料的可行性，并将进行参数研究，以评估电场强度和几何形状，纳米颗粒大小和极化，复杂的流体介电常数和弹性，以及基质固化对形成速率和最终纳米线结构的影响。使用可逆的凝胶，可以形成这种纳米复合材料供临时使用，然后溶解并重新分散以重复使用。使用沿本地电场线线性或分裂的纳米线作为脉管系统模板的溶解，应该可以决定微流体网络的结构和连通性。Broader的影响：在粘合剂中直接形成纳米线复合材料的能力可以简化和简化各种电子设备的处理。组件和底物之间的连接自组装无需精确比对可能会对传感器和显示生产技术产生重大影响。使用拟议的纳米颗粒自组装方法创建微脉管系统可以允许在有限资源（例如在战场上或太空中）的情况下制造微化学过程。该计划将直接教育一名研究生，并在课程，期刊出版物，会议上传播产生的结果，任何美观质量的图像都将集成到目前正在开发的Lehigh Valley Art/Nano项目中。拟议研究的结果将显着影响活跃纳米结构和纳米系统计划的纳米制造和纳米级设备以及系统架构区域。
