项目摘要
This project contributes new knowledge related to laser-based manufacturing which can be used to incorporate novel ultra-low-density functional materials into useful device structures. Bolometers have very broad applications in both civilian and military fields including thermal imaging, night vision, astronomy, security, and particle physics. To achieve high sensitivity and fast response, the bolometer system requires very efficient light absorption, high temperature response of its electrical resistance, very low heat loss to the environment, and very small heat capacitance. Existing bolometers lack wide spectrum response and the performance needs to be improved significantly to meet various needs. This project develops a novel manufacturing process using laser-controlled chemical reactions to make very high sensitivity bolometers that have a fast response time and excellent sensitivity to radiation from ultraviolet to far-infrared. The laser-controlled chemical reaction is used to manufacture and tailor graphene aerogels to make sub-micron size bolometers. The project investigates the patterning and chemical, and electrical materials modification using spatial precision available through laser-based manufacturing. The advances made in this work will benefit the U.S. economy and potential national security applications, with the potential to impact the manufacture of other aerogel materials. This research will involve extensive graduate and undergraduate student training and education outreach to K-12 graders.Because of its excellent photon absorption properties and porous structure, graphene aerogel has both a very high (close to 100%) and wideband photon absorption (ultraviolet to millimeter). Current graphene aerogel manufacturing processes cannot be directly used for making micron-scale bolometers Laser-based manufacturing has the additional potential to provide materials modification with high spatial resolution and optimized control over the changes in materials properties. Addressing the device need, this project is designed to develop a laser-controlled chemical reduction technique allowing for the direct manufacturing of graphene aerogel-based bolometers down to sub-micron scale. The research team will develop laser-controlled chemical reduction and N-doping for direct manufacturing of graphene aerogel bolometers of highly defined size (down to sub-µm) with direct and scalable integration to microscale circuits. The effect of laser parameters will be investigated to uncover the relations between manufacturing conditions and graphene aerogel structure and properties. Via tailoring the surface functional groups within the graphene aerogel, the research team will significantly optimize the sensitivity of GA bolometers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
该项目贡献了与激光制造相关的新知识,可用于将新型超低密度功能材料融入有用的设备结构中。辐射热测量计在民用和军事领域都有非常广泛的应用,包括热成像、夜视、天文学、安全和粒子物理。为了实现高灵敏度和快速响应,测辐射热计系统需要非常高效的光吸收、其电阻的高温响应、对环境的热损失非常低以及热容非常小。现有的辐射热测量计缺乏宽光谱响应,其性能需要显着提高才能满足各种需求。该项目开发了一种新颖的制造工艺,利用激光控制的化学反应来制造非常高灵敏度的辐射热测量计,该辐射热测量计具有快速的响应时间和对从紫外线到远红外线辐射的出色敏感性。激光控制的化学反应用于制造和定制石墨烯气凝胶,以制造亚微米尺寸的测辐射热计。该项目利用基于激光的制造提供的空间精度来研究图案化以及化学和电气材料的改性。这项工作取得的进展将有利于美国经济和潜在的国家安全应用,并有可能影响其他气凝胶材料的制造。这项研究将涉及对 K-12 年级学生进行广泛的研究生和本科生培训和教育推广。由于其优异的光子吸收特性和多孔结构,石墨烯气凝胶既具有非常高(接近 100%)又具有宽带光子吸收(紫外线到毫米)。目前的石墨烯气凝胶制造工艺不能直接用于制造微米级测辐射热计。基于激光的制造具有额外的潜力,可以提供具有高空间分辨率的材料改性以及对材料性能变化的优化控制。为了满足设备需求,该项目旨在开发一种激光控制的化学还原技术,允许直接制造亚微米级的基于石墨烯气凝胶的测辐射热计。研究团队将开发激光控制的化学还原和氮掺杂,用于直接制造高度限定尺寸(低至亚微米)的石墨烯气凝胶测辐射热计,并直接且可扩展地集成到微型电路中。将研究激光参数的影响,以揭示制造条件与石墨烯气凝胶结构和性能之间的关系。通过定制石墨烯气凝胶内的表面官能团,研究团队将显着优化 GA 测辐射热计的灵敏度。该奖项反映了 NSF 的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准进行评估,被认为值得支持。
