This NSF award to University of Massachusetts Amherst funds U.S. researchers participating in a project competitively selected by the G8 Research Councils Initiative ?Structural Bamboo Products.? This is a pilot collaboration among the U.S. National Science Foundation, the Canadian National Sciences and Engineering Research Council (NSERC), the French Agence Nationale de la Recherche (ANR), the German Deutsche Forschungsgemeinschaft (DFG), the Japan Society for the Promotion of Science (JSPS), the Russian Foundation for Basic Research (RFBR),and the United Kingdom Research Councils (RCUK), supporting collaborative research projects selected on a competitive basis that are comprised of researchers from at least three of the partner countries. This multi-national collaboration--Methods for Materials-efficient Manufacturing (M3)-- will perform research on polymer-nanoparticle hybrid materials for sustainable production of advanced technology devices. The M3 team includes the University of Massachusetts Amherst and Rutgers University (U.S.), Tohoku University and the University of Tokyo (Japan), and Institut de Chimie de la Matière condensée de Bordeaux and the UMR CNRS Environnement, Ville, Société (France). The M3 research program focuses on solution-based processing of devices, device layers, components and functional materials on a roll-to-roll production platform, in which hybrid materials containing both polymers and nanoparticles are used to generate functional devices on flexible substrates. One technical goal for the project is development of solution-coatable high dielectric constant device layers comprised of polymer/nanoparticle composites; these layers are the active components of working devices, and progress in this field will advance efficient roll-to-roll flexible device production. A second technical goal is the use of polymer/nanoparticle solutions to form highly transparent emissive nanocomposite films containing optically active nanoparticles, including rare-earth dopes phosphors, as the functional component. U.S. research activities focus on developing the polymer hybrid materials and roll-to-roll processing methods (UMass Amherst), and synthesizing and characterizing the optically active composites (Rutgers). The outcomes from this multinational research project will lead to more materials-efficient and sustainable manufacturing of materials and devices for applications such as energy conversion and storage, flexible electronics and displays, and optoelectronics. Compared to conventional batch vacuum and deposition processes, the solution-based roll-to-roll process can afford lower cost, less waste and significantly lower energy inputs. When combined with innovations in the materials used in the coating process for device fabrication, it is expected that the resultant process will involve fewer steps, no batch changes, commodity-priced materials, lower process temperatures, and drastically lower water usage, thereby reducing direct energy consumption.

这项授予马萨诸塞州阿默斯特大学的NSF奖项为参与八国集团研究理事会倡议竞争性选择的项目的美国研究人员提供资金？结构竹产品。这是美国国家科学基金会、加拿大国家科学和工程研究理事会（NSERC）、法国国家研究机构（ANR）、德国研究共同体（DFG）、日本科学促进协会（JSPS）、俄罗斯基础研究基金会（RFBR）和英国研究理事会（RCUK）之间的试点合作。支持在竞争基础上选定的由至少三个伙伴国家的研究人员组成的合作研究项目。这项多国合作-材料高效制造方法（M3）-将对聚合物-纳米颗粒混合材料进行研究，以实现先进技术设备的可持续生产。M3团队包括马萨诸塞州阿默斯特大学和罗格斯大学（美国），东北大学和东京大学（日本）、波尔多浓缩物化学研究所和法国城市研究中心CNRS环境公司（法国）。M3研究计划的重点是在卷对卷生产平台上对设备、设备层、组件和功能材料进行基于解决方案的加工，其中包含聚合物和纳米颗粒的混合材料用于在柔性基板上生成功能设备。该项目的一个技术目标是开发由聚合物/纳米颗粒复合材料组成的可溶液涂覆的高介电常数器件层;这些层是工作器件的有源组件，该领域的进展将促进高效的卷对卷柔性器件生产。第二个技术目标是使用聚合物/纳米颗粒溶液来形成含有光学活性纳米颗粒（包括稀土掺杂磷光体）作为功能组分的高度透明的发射纳米复合材料膜。美国的研究活动集中在开发聚合物混合材料和卷对卷加工方法（马萨诸塞大学阿默斯特分校），以及合成和表征光学活性复合材料（罗格斯大学）。这一跨国研究项目的成果将为能源转换和储存、柔性电子和显示器以及光电子等应用带来更高的材料效率和可持续性的材料和设备制造。与传统的批量真空和沉积工艺相比，基于溶液的卷对卷工艺可以提供更低的成本、更少的浪费和显著更低的能源投入。当与用于设备制造的涂层工艺中使用的材料的创新相结合时，预计所得到的工艺将涉及更少的步骤，没有批次变化，商品价格的材料，更低的工艺温度，以及大大降低的用水量，从而减少直接能耗。
