项目摘要
In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program in the Division of Chemistry, Professor Zhiqun Lin of the School of Materials Science and Engineering at the Georgia Institute of Technology is developing a new class of nanomaterials which contain polymers on their surfaces that are responsive to light. Nanoparticles are very tiny particles about 500-100,000 times "thinner" than a human hair. However, they have surface area to volume ratios orders of magnitudes larger than seen in traditional materials such as steel, wood, concrete or plastic. As a matter of fact, just a couple of grams of such particles can have an area as enormous as a football field. Combining nanoparticles in a controlled manner to create materials with useful properties is often very tedious and challenging synthetic task. This work greatly simplifies the assembly of nanoparticles into materials by utilizing precisely designed polymers on their surfaces. These polymers when activated by light drive nanoparticles to combine in a controlled manner and therefore act as a photo-switch. Such control by a virtue of polymer architecture and chemistry has the potential to provide important knowledge that could impact the development of useful stimuli-responsive technologies that are often seen in optical cables used for high speed internet, durable "smart fabrics", light sensors, and even drug delivery in cancer therapy. The work has a broader impact through the development of several activities and programs that focus on education of students, especially women and students from underrepresented groups. The research team is further broadening the impact of their work by including and mentoring high school teachers from the greater Atlanta area.This research is focused on the synthesis and reversible self-assembly of monodisperse plasmonic nanorods permanently ligated with photo-responsive polymers. The innovative and highly transformative strategy is focused on (a) designing and crafting monodisperse polymer-tethered plasmonic gold nanorods and nanotubes with accurate control over their dimension, (b) systematic exploration of their structure-dependent optical properties and (c) investigation into light-enabled self-assembly of particles intimately and permanently capped with photo-responsive polymers, and accordingly the reversible optical properties. The knowledge gained from the project has the potential to impact the development of technologies with applications in optics, optoelectronics, catalysis, sensory materials and devices, energy conversion, drug delivery, nanotechnology and biotechnology.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.
在该项目由化学系的大分子,超分子和纳米化学计划资助的项目中,乔治亚技术学院材料科学与工程学院的Zhiqun Lin教授正在开发一种新的纳米材料类,其中包含对光线响应光线的聚合物的新纳米材料。 纳米颗粒是比人头发大约500-100,000倍的小颗粒。 但是,它们具有比钢,木材,混凝土或塑料等传统材料大的幅度比例的表面积与体积比顺序。 事实上,只有几克此类粒子可以拥有像足球场一样巨大的区域。以受控的方式组合纳米颗粒以创建有用特性的材料通常是非常乏味且具有挑战性的合成任务。 这项工作通过在其表面上使用精确设计的聚合物来大大简化纳米颗粒的组装中。 这些聚合物被轻驱动纳米颗粒激活以控制方式合并,因此充当照相开关。 通过聚合物结构和化学的控制,这种控制有可能提供重要的知识,这些知识可能会影响有用的刺激性反应性技术的发展,这些技术通常在用于高速互联网的光电缆中可见,耐用的“智能织物”,轻型传感器,甚至在癌症治疗中提供药物输送。 这项工作通过开发几项专注于学生教育的活动和计划,尤其是来自代表性不足的妇女的学生和学生,从而产生了更大的影响。 研究团队通过包括和指导来自大亚特兰大地区的高中教师的指导和指导高中教师的影响进一步扩大其作品的影响。这项研究的重点是与光子反应性聚合物永久连接的单分散等离子纳米棒的综合和可逆自组装。 创新和高度变革性的策略集中在(a)设计和制作单分散聚合物系列的等离子金纳米棒和纳米管,以准确控制其尺寸,((b)系统探索其结构依赖性光学特性,并(c)对光线构成的颗粒和永久性互联面的自动化,并将其(c)与颗粒相结合,并逐渐融合,并逐渐融合,并逐渐融合,并逐渐融合,并逐渐融合了相同的相同,并逐渐融合了彼此的相同范围,并逐渐融合了彼此的相同范围,并逐渐相处融合,并逐渐融合了彼此的相关性,并逐渐相处融合,并逐渐融合了彼此的相关性,并逐渐融合了相关的相关性。光学特性。 从项目中获得的知识有可能影响技术的开发,并在光学,光电学,催化,感官材料和设备,能量转换,药物输送,纳米技术和生物技术方面的应用中都具有影响。这奖反映了NSF的法定任务,并通过评估基础的智力效果和宽阔的范围来评估,并被视为值得通过评估来进行评估。
